Usually the RPM's work fine if they're build for that version of operating
system.
What I tend to do is not trust RPM to do the update correctly (particularly
with postgres).
So normally for an upgrade I:
pg_dumpall > backup.dump
shut down the postmaster
make a backup copy of the old data directory (usually /var/lib/pgsql)
do an rpm -e on all postgres and libpq packages.
make sure /var/lib/pgsql is gone now
install the new version from the rpms which should create a complete setup and
also do the initdb for you.
then restore the databases as postgres user with
psql template1 < backup.dump
do a vacuum full analyze verbose on all databases
If that went all well you should have all your data back in place. You may
have to fiddle with the postgres.conf and pg_hba.conf settings, because
removing the old postgres version will also erase those files. So you may
want to keep a copy around for reference.
Hope that helps
