I'm wanting to test the most recent version of postgresql, so I went to yum.postgresql.org and started looking in the repo for stuff to download. Nearly every component there has 3 rpms, a rc1 copy in addition to a 1 and 2 rpm. My question is, do I need the rc1 rpm in addition to the 1 & 2 rpm's? Or which ones do I need exactly for each component? I've done a little digging on the site, and I didn't really find any guidance.
