The oledb driver PostgreSQL doesn't support Delphi (and a lot of other
things). My gut feeling is it probably never will...most people who
use the ms stack use the odbc or the .net drivers.
My personal favorite connection library to Delphi is Zeos...it's a
little cranky to set up but extremely fast and powerful. It has a
client side sql parser that allows very advanced data binding.
