redhat and postgresql management

[David Bear <David.Bear@xxxxxxx>]

I have RHEL 5.4 (64bit) that has a postgresql-lib 8.1 installed to satisfy dependancy for a dozen other packages including apache, php and other apache modules, and subversion.

I want to install postresql 8.3 but yum informs me of the version conflict of the library. May i safely just over write the postgresql-lib with the 8.3 lib ?? I'd rather not have to uninstall all the dependancies, install pg, then reinstall everything I just removed facing more possible dependacy issue. 

any advice much appreciated.
