Usually PostgreSQL data file formats are not compatible between major
releases, e.g. between 7.2.x and 7.3.x.

You can delete the directories containing the data files
(don't know where they will be on RedHat, try /var/db )
and create a new database "cluster" using the initdb
installed with 7.3.1.
See e.g.:
http://www.ca.postgresql.org/users-lounge/docs/7.3/postgres/creating-cluster.html
(If you suddenly find you want the old data you can alway reinstall
7.2.x, dump the data and import it in to 7.3.x, see:
http://www.ca.postgresql.org/users-lounge/docs/7.3/postgres/backup.html )
