redhat 7.1 upgrade

anyone have any recommendations on upgrading postgresql on a redhat 7.1
system?

there are no redhat 7.1 rpms for postgresql 7.2 or 7.3. the 7.3 rpms
require a newer version of openssl, and that wants to drag in all kinds of
stuff.

it's an operational box, i am reluctant to take too many risks, but
there's nothing operational dependent on postgresql right now, so i can
take some risks there. anyone got a method that works?

note that when i eventually upgrade the redhat installation on this box, i
would like to go back to rpm installs if i have to get away from that now.

thanks,
  richard
