As far as I am aware DBI does not currently have a PostgreSQL driver.  To 
connect to PostgreSQL you can use RODBC (easy) or RdbiPgSQL (and Rdbi) 
from Bioconductor, which uses a precursor to DBI.  Unfortunately, I don't 
see a Windows binary for RdbiPgSQL on the Bioconductor site so you would 
need to compile it from sources (not easy).
