Release 7.3
-

Release date: 2002-11-27
_________________________________________________________________
-
+
Overview
-
+
Major changes in this release:
-
+
Schemas
Schemas allow users to create objects in separate namespaces,
so two people or applications can have tables with the same
name. There is also a public schema for shared tables.
Table/index creation can be restricted by removing permissions
on the public schema.
-
+
Drop Column
PostgreSQL now supports the ALTER TABLE ... DROP COLUMN
functionality.
-
+
Table Functions
Functions returning multiple rows and/or multiple columns are
now much easier to use than before. You can call such a "table
function" in the SELECT FROM clause, treating its output like a
table. Also, PL/pgSQL functions can now return sets.
-
+
Prepared Queries
PostgreSQL now supports prepared queries, for improved
performance.
-
+
Dependency Tracking
PostgreSQL now records object dependencies, which allows
improvements in many areas. "DROP" statements now take either
CASCADE or RESTRICT to control whether dependent objects are
also dropped.
-
+
Privileges
Functions and procedural languages now have privileges, and
functions can be defined to run with the privileges of their
creator.
-
+
Internationalization
Both multibyte and locale support are now always enabled.
-
+
Logging
A variety of logging options have been enhanced.
-
+
Interfaces
A large number of interfaces have been moved to
http://gborg.postgresql.org where they can be developed and
released independently.
-
+
Functions/Identifiers
By default, functions can now take up to 32 parameters, and
identifiers can be up to 63 bytes long. Also, OPAQUE is now
deprecated: there are specific "pseudo-datatypes" to represent
each of the former meanings of OPAQUE in function argument and
result types.
_________________________________________________________________
-
+
Migration to version 7.3
-
+
A dump/restore using pg_dump is required for those wishing to migrate
data from any previous release. If your application examines the
system catalogs, additional changes will be required due to the
introduction of schemas in 7.3; for more information, see:
http://www.ca.postgresql.org/docs/momjian/upgrade_tips_7.3.
-
+
Observe the following incompatibilities:
-
+
* Pre-6.3 clients are no longer supported.
* "pg_hba.conf" now has a column for the user name and additional
features. Existing files need to be adjusted.
@@ -436,9 +417,9 @@
* An empty string ('') is no longer allowed as the input into an
integer field. Formerly, it was silently interpreted as 0.

Overview
-
+
This release improves PostgreSQL for use in high-volume applications.
-
+
Major changes in this release:
-
+
VACUUM
Vacuuming no longer locks tables, thus allowing normal user
access during the vacuum. A new "VACUUM FULL" command does
old-style vacuum by locking the table and shrinking the on-disk
copy of the table.
-
+
Transactions
There is no longer a problem with installations that exceed
four billion transactions.
-
+
OIDs
OIDs are now optional. Users can now create tables without OIDs
for cases where OID usage is excessive.
-
+
Optimizer
The system now computes histogram column statistics during
"ANALYZE", allowing much better optimizer choices.
-
+
Security
A new MD5 encryption option allows more secure storage and
transfer of passwords. A new Unix-domain socket authentication
option is available on Linux and BSD systems.
-
+
Statistics
Administrators can use the new table access statistics module
to get fine-grained information about table and index usage.
-
+
Internationalization
Program and library messages can now be displayed in several
languages.

The previous C function manager did not handle null values

use the new function manager call interface.

This release contains improvements in many areas, demonstrating the
continued growth of PostgreSQL. There are more improvements and fixes
in 7.0 than in any previous release. The developers have confidence
that this is the best release yet; we do our best to put out only
solid releases, and this one is no exception.

Major changes in this release:
-

Foreign Keys
Foreign keys are now implemented, with the exception of PARTIAL
MATCH foreign keys. Many users have been asking for this
feature, and we are pleased to offer it.

+
Optimizer Overhaul
Continuing on work started a year ago, the optimizer has been
improved, allowing better query plan selection and faster
performance with less memory usage.

psql, our interactive terminal monitor, has been updated with a
variety of new features. See the psql manual page for details.

protected from being deleted or updated by concurrent transactions
before the current transaction does a commit or rollback.
-
+
To ensure the actual existence of a row and protect it against
concurrent updates one must use "SELECT FOR UPDATE" or an appropriate
"LOCK TABLE" statement. This should be taken into account when porting
applications from previous releases of PostgreSQL and other
environments.
-
+
Keep the above in mind if you are using "contrib/refint.*" triggers
for referential integrity. Additional techniques are required now. One
way is to use "LOCK parent_table IN SHARE ROW EXCLUSIVE MODE" command
if a transaction is going to update/delete a primary key and use "LOCK
parent_table IN SHARE MODE" command if a transaction is going to
update/insert a foreign key.
-
+
Note: Note that if you run a transaction in SERIALIZABLE mode then
you must execute the "LOCK" commands above before execution of any
DML statement ("SELECT/INSERT/DELETE/UPDATE/FETCH/COPY_TO") in the
transaction.
-
+
These inconveniences will disappear in the future when the ability to
read dirty (uncommitted) data (regardless of isolation level) and true
referential integrity will be implemented.

There are some general 6.3 issues that I want to mention. These are

of the detailed changes list is still needed.

may think. Vadim has put us on the big SQL map with subselects, and

is to use them in the target list.
-
+
Second, 6.3 uses Unix domain sockets rather than TCP/IP by default. To
enable connections from other machines, you have to use the new
postmaster -i option, and of course edit "pg_hba.conf". Also, for this
reason, the format of "pg_hba.conf" has changed.
-
+
Third, char() fields will now allow faster access than varchar() or
text. Specifically, the text and varchar() have a penalty for access
to any columns after the first column of this type. char() used to
also have this access penalty, but it no longer does. This may suggest
that you redesign some of your tables, especially if you have short
character columns that you have defined as varchar() or text. This and
other changes make 6.3 even faster than earlier releases.
-
+
We now have passwords definable independent of any Unix file. There
are new SQL USER commands. See the Administrator's Guide for more
information. There is a new table, pg_shadow, which is used to store
user information and user passwords, and it by default only
SELECT-able by the postgres super-user. pg_user is now a view of
pg_shadow, and is SELECT-able by PUBLIC. You should keep using pg_user
in your application without changes.
-
+
User-created tables now no longer have SELECT permission to PUBLIC by
default. This was done because the ANSI standard requires it. You can
of course GRANT any permissions you want after the table is created.
System tables continue to be SELECT-able by PUBLIC.
-
+
We also have real deadlock detection code. No more sixty-second
timeouts. And the new locking code implements a FIFO better, so there
should be less resource starvation during heavy use.
-
+
Many complaints have been made about inadequate documentation in
previous releases. Thomas has put much effort into many new manuals
for this release. Check out the doc/ directory.
-
+
For performance reasons, time travel is gone, but can be implemented
using triggers (see "pgsql/contrib/spi/README"). Please check out the
new \d command for types, operators, etc. Also, views have their own
permissions now, not based on the underlying tables, so permissions on
them have to be set separately. Check "/pgsql/interfaces" for some new
ways to talk to PostgreSQL.
-
+
This is the first release that really required an explanation for
existing users. In many ways, this was necessary because the new
release removes many limitations, and the work-arounds people were
using are no longer needed.

In upgrading from version 6.2, if you choose to dump/reload you will
find that avg(money) is now calculated correctly. All other bug fixes
take effect upon updating the executables.

The regression tests have been adapted and extensively modified for

Three new data types (datetime, timespan, and circle) have been added
to the native set of PostgreSQL types. Points, boxes, paths, and
polygons have had their output formats made consistent across the data
types. The polygon output in misc.out has only been spot-checked for
correctness relative to the original regression output.

The interpretation of array specifiers (the curly braces around atomic

tests were generated. The current "./expected/*.out" files reflect
this new interpretation, which may not be correct!

The float8 regression test fails on at least some platforms. This is
due to differences in implementations of pow() and exp() and the
signaling mechanisms used for overflow and underflow conditions.

The "random" results in the random test should cause the "random" test
to be "failed", since the regression tests are evaluated using a
simple diff. However, "random" does not seem to produce random results
on my test machine (Linux/gcc/i686).
