DBD::PgPP is what you need. As CPAN Says "DBD::PgPP is a Pure Perl client interface for the PostgreSQL database. This module implements network protocol between server and client of PostgreSQL, thus you don't need external PostgreSQL client library like libpq for this module to work. It means this module enables you to connect to PostgreSQL server from some operation systems which PostgreSQL is not ported. How nifty!"

Since PostgreSQL doesnt appear to be ported, this should be the solution
