Since DBI uses a different DBD for every database, you should get
the DBD for PostgreSQL (DBD:Pg) from your local perl archive...

This DBD really should be in the distribution.

Pg.pm is not in any way connected to DBI. It is marginally faster
than DBI, but you loose the ability to choose between different
databases.
