Setting up Postfix with PosgreSQLon FreeBSD

[Bill Schmitt (SW)]

I've been trying to find some documentation on setting up Postfix to use 
PostgreSQL on FreeBSD. There seems to be a lot of documentation on doing 
it with mySQL, but I can't seem to find anything using PostgreSQL. Does 
anyone here have any documentation, suggestions, or pointers to web 
sites? I'm working with FBSD 4.9, PostgreSQL 7.2, and Postfix 2.15.

TIA,

Bill
