PG does come with RedHat, and you may have chosen it in your install. Did
you install PG 7.2 from source? If so, it will be in /usr/local/pgsql
(unless you chose non-default options for ./configure), where the RedHat RPM
is installed in several places (as the RPM standard suggests). Probably
/usr/bin, where PG7.1 would be, is higher in your $PATH that
/usr/local/pgsql/bin, where PG7.2 is.

Try:

# rpm -qa | grep -i postgres

To find all RPMs on your system relating to PG.

You can uninstall these with

# rpm -e <list of RPMs>
