3/25    Do you need to install a special DBI module for PostgreSQL or it's
        built in Perl5 already?
        \_ AFAIK, you need the correct DBD module (Pg.pm) for PostgreSQL.
           This isn't part of Perl. On RH you can install a perl-DBD-Pg-1.x
           rpm which should include everything you need. On FreeBSD make
           install in /usr/ports/databases/p5-DBD-Pg should give you
           everything you need.
           \_ and of course apt-get install libdbd-pg-perl
