Hello Alan,
From /usr/doc/postgresql-7.0.2/README.rpm it says...;-)
NOTE: The 7.0 RPMs are only being built under RedHat 6.2! They
may or may not work under RedHat 6.0 or 6.1.
But like you, I have come across the exact same thing...;-) _IF_ you
don't have any real data and are willing to start from scratch... try
deleting all files and directories under
/var/lib/pgsql
and re-run your postgresql start-up script.... Postgresql should create
an empty database for your perusal...;-)
If you have some important data... Well then, I strongly recommend that
you back-up your data from the
/var/lib/pgsql
directory before proceeding to delete all file and directories under
it...;-)
Hope that helps...;-)
Cheers,
John Clark
