DBD::PgPP ========= DBD::PgPP - Pure-Perl DBI driver for the PostgreSQL database DBD::PgPP is a pure-Perl client interface for the PostgreSQL database. This module implements the network protocol that allows a client to communicate with a PostgreSQL server, so you don't need an external PostgreSQL client library like libpq for it to work. That means this module enables you to connect to PostgreSQL server from platforms where there's no PostgreSQL port, or where installing PostgreSQL is prohibitively hard. DEPENDENCIES ------------ This module uses the following other modules and libraries: DBI IO::Socket (ships with supported Perl versions) Digest::MD5 (ships with supported Perl versions) INSTALLATION ------------ To install this module, run the following: perl Makefile.PL make make test make install TESTING ------- The test suite requires access to a suitable PostgreSQL server; without that, only an extremely limited form of testing is possible. To tell the test suite how to find a PostgreSQL server, set the following environment variables: DBI_DSN (required) A DBI "data source name" indicating the location of the database. For example, to connect to the database named "abc" over a Unix-domain socket stored in /var/run/postgresql, use this DSN: export DBI_DSN='dbi:PgPP:dbname=abc;path=/var/run/postgresql' Or to connect to a database of the same name, using a TCP connection to pg.example.com, use this: export DBI_DSN='dbi:PgPP:dbname=abc;host=pg.example.com' See the DBD::PgPP documentation for full details on what can go into a DBD::PgPP DSN. DBI_USER (optional) The username to connect as; defaults to the database name DBI_PASS (optional) The password needed to allow the given user to authenticate to the server. Some configurations of PostgreSQL allow connection without a password; you don't need to set a DBI_PASS in such cases. Note that DBD::PgPP 0.05 and earlier versions used a different set of environment variables for telling the test suite how to contact the database. The new variables are more flexible, more consistent with how Perl code connects to a database, and more consistent with how other DBDs (including DBD::Pg) accomplish the same task. REPORTING BUGS -------------- If you find what seems to be a bug in DBD::PgPP, please use RT to report it to the maintainers: http://rt.cpan.org/NoAuth/Bugs.html?Dist=DBD-PgPP Please supply any information that could help with reproducing the bug. For example, if the bug only appears when DBD::PgPP is used with certain database schemas, a description (or even a dump) of the schema in question would be useful. MAINTENANCE ----------- The current maintainer of DBD::PgPP no longer has cause to use it, and would welcome the assistance of anyone who does -- or even a volunteer to take over maintenance completely. Even if you aren't in a position to do that, please report any bugs you find; and if you want a new feature, please send tests for it (with or without a sample implementation). The code is hosted on GitHub, which should hopefully make it easy for others to contribute. The clone URL is: git://github.com/arc/dbd-pgpp.git Feel free to fork and send me a pull request.
