If you care about the data in the 7.3 data directory, you will
have to migrate it: start a 7.3 server, export with 8.3's
pg_dumpall, run 8.3's initdb, import the dump.
and thats not that easy with Redhat/Centos/Fedora/etc RPM installs, as
installing 8.x from RPM sources wiped out the 7.3 binaries
assuming you installed the PGDG rpms over the RH stock 7.3 RPMs, and you
don't particluarlly care for any 7.3 databases, you could try this...
# service stop postgresql -- (make sure everything is
stopped)
# mv /var/lib/pgsql/data /var/lib/pgsql/data-73
# service postgresql initdb
# service postgresql start
this will put aside the 7.3 postgres data for later consideration, and
create a new database cluster with the version you installed.
