You can have Windows interface with Postgress easily using ODBC. Download psqlodbc.dll. There is a link on www.postgresql.org
I think. The name is "Postgres-ODBC driver". Once you get the dll and register it, you will see Postgres as an option in your ODBC system DSN list. If you download the self-installing version, it will register the DLL for you.
If not, put in system32 folder and use
on command line to register.
