DBI and DBD are (families of) Perl modules.  DBI is a fairly
high level of abstration for dealing with DataBase Interfaces
(hence the name DBI).  DBD modules are the DataBase Drivers
used by the DBI to talk to the actual database.  You can get
the DBI module, and the particular DBD (in this case, it's
PG for PostgreSQL) from some place called CPAN (Comprehensive
Perl Archive Network) at http://www.cpan.org/  I am a Debian
user, so I don't know how much of CPAN is available from Redhat.
Certainly a good chunk of CPAN is available using apt-get from
Debian (but they always change the names of the modules).  If
DBI and DBD::Pg are not available from Redhat, hopefully they
do have cpan.pm available, which is a relatively painless
way of downloading, compiling, testing and installing perl
modules from CPAN.
