Most Perl users are familiar with using Perl to talk to databases. Perl’s DBI is, along with ODBC and JDBC, one of the most common and widely ported database client interfaces. The DBI driver for PostgreSQL, DBD::Pg, is very well-maintained, and quite featureful. For example, it recently acquired proper support for prepared statements. Previously, the client library had emulated these, but with the latest DBD::Pg and PostgreSQL distributions, you can get real prepared queries, which can lead to big performance gains in some cases.
