Installing postgresql

Howdy,

I would like to evaluate postgresql. I want to install the RPM version
on a redhat 7.1 server. I looked at the files at
http://planetmirror.com/pub/postgresql/binary/v7.2.1/RPMS/ but I can't
tell which files I need. And if they are for an intel linux why do they
have the name sparc appended at the end?


Thanks for your help,

Jeff
