PostgreSQL Installation Instructions
This document describes the installation of PostgreSQL from the source code
distribution.
-------------------------------------------------------------------------------
Short Version
./configure
gmake
su
gmake install
adduser postgres
mkdir /usr/local/pgsql/data
chown postgres /usr/local/pgsql/data
su - postgres
/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 &
/usr/local/pgsql/bin/createdb test
/usr/local/pgsql/bin/psql test
The long version is the rest of this document.
-------------------------------------------------------------------------------
Requirements
In general, a modern Unix-compatible platform should be able to run PostgreSQL.
The platforms that had received specific testing at the time of release are
listed in the Section called Supported Platforms below. In the "doc"
subdirectory of the distribution there are several platform-specific FAQ
documents you might wish to consult if you are having trouble. The following
software packages are required for building PostgreSQL:
* GNU make is required; other make programs will *not* work. GNU make is
often installed under the name "gmake"; this document will always refer
to it by that name. (On some systems GNU make is the default tool with
the name "make".) To test for GNU make enter
gmake --version
It is recommended to use version 3.76.1 or later.
* You need an ISO/ANSI C compiler. Recent versions of GCC are
recommendable, but PostgreSQL is known to build with a wide variety of
compilers from different vendors.
* gzip is needed to unpack the distribution in the first place. If you are
reading this, you probably already got past that hurdle.
* The GNU Readline library (for comfortable line editing and command
history retrieval) will be used by default. If you don't want to use it
then you must specify the "--without-readline" option for "configure".
(On NetBSD, the "libedit" library is Readline-compatible and is used if
"libreadline" is not found.)
* To build on Windows NT or Windows 2000 you need the Cygwin and cygipc
packages. See the file "doc/FAQ_MSWIN" for details.
The following packages are optional. They are not required in the default
configuration, but they are needed when certain build options are enabled, as
explained below.
* To build the server programming language PL/Perl you need a full Perl
installation, including the "libperl" library and the header files. Since
PL/Perl will be a shared library, the "libperl" library must be a shared
library also on most platforms. This appears to be the default in recent
Perl versions, but it was not in earlier versions, and in general it is
the choice of whomever installed Perl at your site.
If you don't have the shared library but you need one, a message like
this will appear during the build to point out this fact:
*** Cannot build PL/Perl because libperl is not a shared library.
*** You might have to rebuild your Perl installation. Refer to
*** the documentation for details.
(If you don't follow the on-screen output you will merely notice that the
PL/Perl library object, "plperl.so" or similar, will not be installed.)
If you see this, you will have to rebuild and install Perl manually to be
able to build PL/Perl. During the configuration process for Perl, request
a shared library.
* To build the PL/Python server programming language, you need a Python
installation, including the header files. Since PL/Python will be a
shared library, the "libpython" library must be a shared library also on
most platforms. This is not the case in a default Python installation.
If after building and installing you have a file called "plpython.so"
(possibly a different extension), then everything went well. Otherwise
you should have seen a notice like this flying by:
*** Cannot build PL/Python because libpython is not a shared library.
*** You might have to rebuild your Python installation. Refer to
*** the documentation for details.
That means you have to rebuild (part of) your Python installation to
supply this shared library.
The catch is that the Python distribution or the Python maintainers do
not provide any direct way to do this. The closest thing we can offer you
is the information in Python FAQ 3.30. On some operating systems you
don't really have to build a shared library, but then you will have to
convince the PostgreSQL build system of this. Consult the "Makefile" in
the "src/pl/plpython" directory for details.
* If you want to build Tcl or Tk components (clients and the PL/Tcl
language) you of course need a Tcl installation.
* To build the JDBC driver, you need Ant 1.5 or higher and a JDK. Ant is a
special tool for building Java-based packages. It can be downloaded from
the Ant web site.
If you have several Java compilers installed, it depends on the Ant
configuration which one gets used. Precompiled Ant distributions are
typically set up to read a file ".antrc" in the current user's home
directory for configuration. For example, to use a different JDK than the
default, this may work:
JAVA_HOME=/usr/local/sun-jdk1.3
JAVACMD=$JAVA_HOME/bin/java
Note: Do not try to build the driver by calling "ant" or even
"javac" directly. This will not work. Run "gmake" normally as
described below.
* To enable Native Language Support (NLS), that is, the ability to display
a program's messages in a language other than English, you need an
implementation of the Gettext API. Some operating systems have this
built-in (e.g., Linux, NetBSD, Solaris), for other systems you can
download an add-on package from here: http://www.postgresql.org/~petere/
gettext.html. If you are using the Gettext implementation in the GNU C
library then you will additionally need the GNU Gettext package for some
utility programs. For any of the other implementations you will not need
it.
* Kerberos, OpenSSL, or PAM, if you want to support authentication using
these services.
If you are building from a CVS tree instead of using a released source package,
or if you want to do development, you also need the following packages:
* Flex and Bison are needed to build a CVS checkout or if you changed the
actual scanner and parser definition files. If you need them, be sure to
get Flex 2.5.4 or later and Bison 1.875 or later. Other yacc programs can
sometimes be used, but doing so requires extra effort and is not
recommended. Other lex programs will definitely not work.
If you need to get a GNU package, you can find it at your local GNU mirror site
(see http://www.gnu.org/order/ftp.html for a list) or at ftp://ftp.gnu.org/
gnu/.
Also check that you have sufficient disk space. You will need about 65 MB for
the source tree during compilation and about 15 MB for the installation
directory. An empty database cluster takes about 25 MB, databases take about
five times the amount of space that a flat text file with the same data would
take. If you are going to run the regression tests you will temporarily need up
to an extra 90 MB. Use the "df" command to check for disk space.
-------------------------------------------------------------------------------
If You Are Upgrading
The internal data storage format changes with new releases of PostgreSQL.
Therefore, if you are upgrading an existing installation that does not have a
version number "7.4.x", you must back up and restore your data as shown here.
These instructions assume that your existing installation is under the "/usr/
local/pgsql" directory, and that the data area is in "/usr/local/pgsql/data".
Substitute your paths appropriately.
1. Make sure that your database is not updated during or after the backup.
This does not affect the integrity of the backup, but the changed data
would of course not be included. If necessary, edit the permissions in
the file "/usr/local/pgsql/data/pg_hba.conf" (or equivalent) to disallow
access from everyone except you.
2. To back up your database installation, type:
pg_dumpall > outputfile
If you need to preserve OIDs (such as when using them as foreign keys),
then use the "-o" option when running "pg_dumpall".
"pg_dumpall" does not save large objects. Check the documentation if you
need to do this.
To make the backup, you can use the "pg_dumpall" command from the version
you are currently running. For best results, however, try to use the
"pg_dumpall" command from PostgreSQL 7.4, since this version contains
bug fixes and improvements over older versions. While this advice might
seem idiosyncratic since you haven't installed the new version yet, it is
advisable to follow it if you plan to install the new version in parallel
with the old version. In that case you can complete the installation
normally and transfer the data later. This will also decrease the
downtime.
3. If you are installing the new version at the same location as the old one
then shut down the old server, at the latest before you install the new
files:
kill -INT `cat /usr/local/pgsql/data/postmaster.pid`
Versions prior to 7.0 do not have this "postmaster.pid" file. If you are
using such a version you must find out the process ID of the server
yourself, for example by typing "ps ax | grep postmaster", and supply it
to the "kill" command.
On systems that have PostgreSQL started at boot time, there is probably a
start-up file that will accomplish the same thing. For example, on a Red
Hat Linux system one might find that
/etc/rc.d/init.d/postgresql stop
works. Another possibility is "pg_ctl stop".
4. If you are installing in the same place as the old version then it is
also a good idea to move the old installation out of the way, in case you
have trouble and need to revert to it. Use a command like this:
mv /usr/local/pgsql /usr/local/pgsql.old
After you have installed PostgreSQL 7.4, create a new database directory and
start the new server. Remember that you must execute these commands while
logged in to the special database user account (which you already have if you
are upgrading).
/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
Finally, restore your data with
/usr/local/pgsql/bin/psql -d template1 -f outputfile
using the *new* psql.
These topics are discussed at length in the documentation, which you are
encouraged to read in any case.
-------------------------------------------------------------------------------
Installation Procedure
1. Configuration
The first step of the installation procedure is to configure the source
tree for your system and choose the options you would like. This is done
by running the "configure" script. For a default installation simply
enter
./configure
This script will run a number of tests to guess values for various system
dependent variables and detect some quirks of your operating system, and
finally will create several files in the build tree to record what it
found. (You can also run "configure" in a directory outside the source
tree if you want to keep the build directory separate.)
The default configuration will build the server and utilities, as well as
all client applications and interfaces that require only a C compiler.
All files will be installed under "/usr/local/pgsql" by default.
You can customize the build and installation process by supplying one or
more of the following command line options to "configure":
--prefix=PREFIX
Install all files under the directory "PREFIX" instead of "/usr/
local/pgsql". The actual files will be installed into various
subdirectories; no files will ever be installed directly into the
"PREFIX" directory.
If you have special needs, you can also customize the individual
subdirectories with the following options.
--exec-prefix=EXEC-PREFIX
You can install architecture-dependent files under a different
prefix, "EXEC-PREFIX", than what "PREFIX" was set to. This can be
useful to share architecture-independent files between hosts. If
you omit this, then "EXEC-PREFIX" is set equal to "PREFIX" and both
architecture-dependent and independent files will be installed
under the same tree, which is probably what you want.
--bindir=DIRECTORY
Specifies the directory for executable programs. The default is
"EXEC-PREFIX/bin", which normally means "/usr/local/pgsql/bin".
--datadir=DIRECTORY
Sets the directory for read-only data files used by the installed
programs. The default is "PREFIX/share". Note that this has nothing
to do with where your database files will be placed.
--sysconfdir=DIRECTORY
The directory for various configuration files, "PREFIX/etc" by
default.
--libdir=DIRECTORY
The location to install libraries and dynamically loadable modules.
The default is "EXEC-PREFIX/lib".
--includedir=DIRECTORY
The directory for installing C and C++ header files. The default is
"PREFIX/include".
--docdir=DIRECTORY
Documentation files, except "man" pages, will be installed into
this directory. The default is "PREFIX/doc".
--mandir=DIRECTORY
The man pages that come with PostgreSQL will be installed under
this directory, in their respective "manx" subdirectories. The
default is "PREFIX/man".
Note: Care has been taken to make it possible to install
PostgreSQL into shared installation locations (such as "/usr/
local/include") without interfering with the namespace of the
rest of the system. First, the string "/postgresql" is
automatically appended to datadir, sysconfdir, and docdir,
unless the fully expanded directory name already contains the
string "postgres" or "pgsql". For example, if you choose "/usr/
local" as prefix, the documentation will be installed in "/usr/
local/doc/postgresql", but if the prefix is "/opt/postgres",
then it will be in "/opt/postgres/doc". The public C header
files of the client interfaces are installed into includedir
and are namespace-clean. The internal header files and the
server header files are installed into private directories
under includedir. See the documentation of each interface for
information about how to get at the its header files. Finally,
a private subdirectory will also be created, if appropriate,
under libdir for dynamically loadable modules.
--with-includes=DIRECTORIES
"DIRECTORIES" is a colon-separated list of directories that will be
added to the list the compiler searches for header files. If you
have optional packages (such as GNU Readline) installed in a non-
standard location, you have to use this option and probably also
the corresponding "--with-libraries" option.
Example: --with-includes=/opt/gnu/include:/usr/sup/include.
--with-libraries=DIRECTORIES
"DIRECTORIES" is a colon-separated list of directories to search
for libraries. You will probably have to use this option (and the
corresponding "--with-includes" option) if you have packages
installed in non-standard locations.
Example: --with-libraries=/opt/gnu/lib:/usr/sup/lib.
--enable-nls[=LANGUAGES]
Enables Native Language Support (NLS), that is, the ability to
display a program's messages in a language other than English.
"LANGUAGES" is a space separated list of codes of the languages
that you want supported, for example --enable-nls='de fr'. (The
intersection between your list and the set of actually provided
translations will be computed automatically.) If you do not specify
a list, then all available translations are installed.
To use this option, you will need an implementation of the Gettext
API; see above.
--with-pgport=NUMBER
Set "NUMBER" as the default port number for server and clients. The
default is 5432. The port can always be changed later on, but if
you specify it here then both server and clients will have the same
default compiled in, which can be very convenient. Usually the only
good reason to select a non-default value is if you intend to run
multiple PostgreSQL servers on the same machine.
--with-perl
Build the PL/Perl server-side language.
--with-python
Build the PL/Python server-side language.
--with-tcl
Build components that require Tcl/Tk, which are libpgtcl, pgtclsh,
pgtksh, and PL/Tcl. But see below about "--without-tk".
--without-tk
If you specify "--with-tcl" and this option, then the program that
requires Tk (pgtksh) will be excluded.
--with-tclconfig=DIRECTORY, --with-tkconfig=DIRECTORY
Tcl/Tk installs the files "tclConfig.sh" and "tkConfig.sh", which
contain configuration information needed to build modules
interfacing to Tcl or Tk. These files are normally found
automatically at their well-known locations, but if you want to use
a different version of Tcl or Tk you can specify the directory in
which to find them.
--with-java
Build the JDBC driver and associated Java packages.
--with-krb4[=DIRECTORY], --with-krb5[=DIRECTORY]
Build with support for Kerberos authentication. You can use either
Kerberos version 4 or 5, but not both. The "DIRECTORY" argument
specifies the root directory of the Kerberos installation; "/usr/
athena" is assumed as default. If the relevant header files and
libraries are not under a common parent directory, then you must
use the "--with-includes" and "--with-libraries" options in
addition to this option. If, on the other hand, the required files
are in a location that is searched by default (e.g., "/usr/lib"),
then you can leave off the argument.
"configure" will check for the required header files and libraries
to make sure that your Kerberos installation is sufficient before
proceeding.
--with-krb-srvnam=NAME
The name of the Kerberos service principal. postgres is the
default. There's probably no reason to change this.
--with-openssl[=DIRECTORY]
Build with support for SSL (encrypted) connections. This requires
the OpenSSL package to be installed. The "DIRECTORY" argument
specifies the root directory of the OpenSSL installation; the
default is "/usr/local/ssl".
"configure" will check for the required header files and libraries
to make sure that your OpenSSL installation is sufficient before
proceeding.
--with-pam
Build with PAM (Pluggable Authentication Modules) support.
--without-readline
Prevents the use of the Readline library. This disables command-
line editing and history in psql, so it is not recommended.
--with-rendezvous
Build with Rendezvous support.
--disable-spinlocks
Allow the builds to succeed even if PostgreSQL has no CPU spinlock
support for the platform. The lack of spinlock support will result
in poor performance; therefore, this option should only be used if
the build aborts and informs you that the platform lacks spinlock
support.
--enable-thread-safety
Make the client libraries thread-safe. This allows concurrent
threads in libpq and ECPG programs to safely control their private
connection handles.
--without-zlib
Prevents the use of the Zlib library. This disables compression
support in pg_dump. This option is only intended for those rare
systems where this library is not available.
--enable-debug
Compiles all programs and libraries with debugging symbols. This
means that you can run the programs through a debugger to analyze
problems. This enlarges the size of the installed executables
considerably, and on non-GCC compilers it usually also disables
compiler optimization, causing slowdowns. However, having the
symbols available is extremely helpful for dealing with any
problems that may arise. Currently, this option is recommended for
production installations only if you use GCC. But you should always
have it on if you are doing development work or running a beta
version.
--enable-cassert
Enables assertion checks in the server, which test for many "can't
happen" conditions. This is invaluable for code development
purposes, but the tests slow things down a little. Also, having the
tests turned on won't necessarily enhance the stability of your
server! The assertion checks are not categorized for severity, and
so what might be a relatively harmless bug will still lead to
server restarts if it triggers an assertion failure. Currently,
this option is not recommended for production use, but you should
have it on for development work or when running a beta version.
--enable-depend
Enables automatic dependency tracking. With this option, the
makefiles are set up so that all affected object files will be
rebuilt when any header file is changed. This is useful if you are
doing development work, but is just wasted overhead if you intend
only to compile once and install. At present, this option will work
only if you use GCC.
If you prefer a C compiler different from the one "configure" picks then
you can set the environment variable CC to the program of your choice. By
default, "configure" will pick "gcc" unless this is inappropriate for the
platform. Similarly, you can override the default compiler flags with the
CFLAGS variable.
You can specify environment variables on the "configure" command line,
for example:
./configure CC=/opt/bin/gcc CFLAGS='-O2 -pipe'
2. Build
To start the build, type
gmake
(Remember to use GNU make.) The build may take anywhere from 5 minutes to
half an hour depending on your hardware. The last line displayed should
be
All of PostgreSQL is successfully made. Ready to install.
3. Regression Tests
If you want to test the newly built server before you install it, you can
run the regression tests at this point. The regression tests are a test
suite to verify that PostgreSQL runs on your machine in the way the
developers expected it to. Type
gmake check
(This won't work as root; do it as an unprivileged user.) The file "src/
test/regress/README" and the documentation contain detailed information
about interpreting the test results. You can repeat this test at any
later time by issuing the same command.
4. Installing The Files
Note: If you are upgrading an existing system and are going to
install the new files over the old ones, then you should have
backed up your data and shut down the old server by now, as
explained in
the Section called If You Are Upgrading
above.
To install PostgreSQL enter
gmake install
This will install files into the directories that were specified in step
1. Make sure that you have appropriate permissions to write into that
area. Normally you need to do this step as root. Alternatively, you could
create the target directories in advance and arrange for appropriate
permissions to be granted.
You can use gmake install-strip instead of gmake install to strip the
executable files and libraries as they are installed. This will save some
space. If you built with debugging support, stripping will effectively
remove the debugging support, so it should only be done if debugging is
no longer needed. install-strip tries to do a reasonable job saving
space, but it does not have perfect knowledge of how to strip every
unneeded byte from an executable file, so if you want to save all the
disk space you possibly can, you will have to do manual work.
The standard installation provides only the header files needed for
client application development. If you plan to do any server-side program
development (such as custom functions or data types written in C), then
you may want to install the entire PostgreSQL include tree into your
target include directory. To do that, enter
gmake install-all-headers
This adds a megabyte or two to the installation footprint, and is only
useful if you don't plan to keep the whole source tree around for
reference. (If you do, you can just use the source's include directory
when building server-side software.)
Client-only installation: If you want to install only the client
applications and interface libraries, then you can use these commands:
gmake -C src/bin install
gmake -C src/include install
gmake -C src/interfaces install
gmake -C doc install
Uninstallation: To undo the installation use the command "gmake uninstall".
However, this will not remove any created directories.
Cleaning: After the installation you can make room by removing the built files
from the source tree with the command "gmake clean". This will preserve the
files made by the "configure" program, so that you can rebuild everything with
"gmake" later on. To reset the source tree to the state in which it was
distributed, use "gmake distclean". If you are going to build for several
platforms from the same source tree you must do this and re-configure for each
build.
If you perform a build and then discover that your "configure" options were
wrong, or if you change anything that "configure" investigates (for example,
software upgrades), then it's a good idea to do "gmake distclean" before
reconfiguring and rebuilding. Without this, your changes in configuration
choices may not propagate everywhere they need to.
-------------------------------------------------------------------------------
Post-Installation Setup
Shared Libraries
On some systems that have shared libraries (which most systems do) you need to
tell your system how to find the newly installed shared libraries. The systems
on which this is *not* necessary include BSD/OS, FreeBSD, HP-UX, IRIX, Linux,
NetBSD, OpenBSD, Tru64 UNIX (formerly Digital UNIX), and Solaris.
The method to set the shared library search path varies between platforms, but
the most widely usable method is to set the environment variable
LD_LIBRARY_PATH like so: In Bourne shells ("sh", "ksh", "bash", "zsh")
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH
or in "csh" or "tcsh"
setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
Replace /usr/local/pgsql/lib with whatever you set "--libdir" to in step 1. You
should put these commands into a shell start-up file such as "/etc/profile" or
"~/.bash_profile". Some good information about the caveats associated with this
method can be found at http://www.visi.com/~barr/ldpath.html.
On some systems it might be preferable to set the environment variable
LD_RUN_PATH *before* building.
On Cygwin, put the library directory in the PATH or move the ".dll" files into
the "bin" directory.
If in doubt, refer to the manual pages of your system (perhaps "ld.so" or
"rld"). If you later on get a message like
psql: error in loading shared libraries
libpq.so.2.1: cannot open shared object file: No such file or directory
then this step was necessary. Simply take care of it then.
If you are on BSD/OS, Linux, or SunOS 4 and you have root access you can run
/sbin/ldconfig /usr/local/pgsql/lib
(or equivalent directory) after installation to enable the run-time linker to
find the shared libraries faster. Refer to the manual page of "ldconfig" for
more information. On FreeBSD, NetBSD, and OpenBSD the command is
/sbin/ldconfig -m /usr/local/pgsql/lib
instead. Other systems are not known to have an equivalent command.
-------------------------------------------------------------------------------
Environment Variables
If you installed into "/usr/local/pgsql" or some other location that is not
searched for programs by default, you should add "/usr/local/pgsql/bin" (or
whatever you set "--bindir" to in step 1) into your PATH. Strictly speaking,
this is not necessary, but it will make the use of PostgreSQL much more
convenient.
To do this, add the following to your shell start-up file, such as
"~/.bash_profile" (or "/etc/profile", if you want it to affect every user):
PATH=/usr/local/pgsql/bin:$PATH
export PATH
If you are using "csh" or "tcsh", then use this command:
set path = ( /usr/local/pgsql/bin $path )
To enable your system to find the man documentation, you need to add lines like
the following to a shell start-up file unless you installed into a location
that is searched by default.
MANPATH=/usr/local/pgsql/man:$MANPATH
export MANPATH
The environment variables PGHOST and PGPORT specify to client applications the
host and port of the database server, overriding the compiled-in defaults. If
you are going to run client applications remotely then it is convenient if
every user that plans to use the database sets PGHOST. This is not required,
however: the settings can be communicated via command line options to most
client programs.
-------------------------------------------------------------------------------
Getting Started
The following is a quick summary of how to get PostgreSQL up and running once
installed. The main documentation contains more information.
1. Create a user account for the PostgreSQL server. This is the user the
server will run as. For production use you should create a separate,
unprivileged account ("postgres" is commonly used). If you do not have
root access or just want to play around, your own user account is enough,
but running the server as root is a security risk and will not work.
adduser postgres
2. Create a database installation with the "initdb" command. To run "initdb"
you must be logged in to your PostgreSQL server account. It will not work
as root.
root# mkdir /usr/local/pgsql/data
root# chown postgres /usr/local/pgsql/data
root# su - postgres
postgres$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
The "-D" option specifies the location where the data will be stored. You
can use any path you want, it does not have to be under the installation
directory. Just make sure that the server account can write to the
directory (or create it, if it doesn't already exist) before starting
"initdb", as illustrated here.
3. The previous step should have told you how to start up the database
server. Do so now. The command should look something like
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
This will start the server in the foreground. To put the server in the
background use something like
nohup /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data \
</dev/null >>server.log 2>&1 </dev/null &
To stop a server running in the background you can type
kill `cat /usr/local/pgsql/data/postmaster.pid`
In order to allow TCP/IP connections (rather than only Unix domain socket
ones) you need to pass the "-i" option to "postmaster".
4. Create a database:
createdb testdb
Then enter
psql testdb
to connect to that database. At the prompt you can enter SQL commands and
start experimenting.
-------------------------------------------------------------------------------
What Now?
* The PostgreSQL distribution contains a comprehensive documentation set,
which you should read sometime. After installation, the documentation can
be accessed by pointing your browser to "/usr/local/pgsql/doc/html/
index.html", unless you changed the installation directories.
The first few chapters of the main documentation are the Tutorial, which
should be your first reading if you are completely new to SQL databases.
If you are familiar with database concepts then you want to proceed with
part on server administration, which contains information about how to
set up the database server, database users, and authentication.
* Usually, you will want to modify your computer so that it will
automatically start the database server whenever it boots. Some
suggestions for this are in the documentation.
* Run the regression tests against the installed server (using "gmake
installcheck"). If you didn't run the tests before installation, you
should definitely do it now. This is also explained in the documentation.
* By default, PostgreSQL is configured to run on minimal hardware. This
allows it to start up with almost any hardware configuration. The default
configuration is, however, not designed for optimum performance. To
achieve optimum performance, several server parameters must be adjusted,
the two most common being shared_buffers and sort_mem mentioned in the
documentation. Other parameters mentioned in the documentation also
affect performance.
-------------------------------------------------------------------------------
Supported Platforms
PostgreSQL has been verified by the developer community to work on the
platforms listed below. A supported platform generally means that PostgreSQL
builds and installs according to these instructions and that the regression
tests pass.
Note: If you are having problems with the installation on a supported
platform, please write to <pgsql-bugs@postgresql.org> or <pgsql-
ports@postgresql.org>, not to the people listed here.
