Postgres ODBC

Hello, 
I've never used ODBC connections and I need to do one for a system 
I'm programing. 
I would like to know if someone could tell me step by step how to 
connect using Delphi 4.0 or MS Access to a remote postgres database 
that is runing on a Linux Red hat 7.0 server.

Both Linux server and the PC are using the same LAN.

I would really appreciate if you could let me know what drivers I 
need and how could I this work.

Thanks 
Roberto
