Copy your /var/lib/pgsql directory to somewhere safe.

Try installing pgsql on an FC3 computer (or whatever older version you 
were upgrading from). Copy the /var/lib/pgsql contents to it, and maybe 
(!) you'll have a functional database again. Maybe not, though.

Do you have pre-upgrade tape (or CD or whatever) backups of the 
/var/lib/pgsql directory? Those files would be better than the 
post-upgrade ones.

I too learned about Fedora's habit of clobbering pgsql data after 
upgrades the hard way... but I had enough backups to fix things. Backup 
your raw files AND do a pgdumpall every night!
