32 vs 64 bit odbc drivers

Do I need a 64 bit driver to connect to a 64 bit installation of postgres?

 

I don't think I should need it, since the odbc call should not depend on the architecture making the call, but I am at the grasping-at-straws stage of why I can't connect with odbc to one of the databases on one of our servers.

 

If this is an incredably stupid question, I apologize ahead.

 

Thanks!
