upgrade of 7.2.2-1 to 7.3.4 - Mailing list pgsql-admin

Hi,

       I have  postgresql-7.2.2-1. I downloaded the lib, server and
postgresql versions of 7.3.4. If u do an upgrade its gives a dependency
error saying the library file is req for the installed version 7.2.

       Can i do a force install with no dependencies on all the lib,server
and posgresql-7.3.4. Is this acceptable or will it create some problems
