Yeah, this is a known problem in some earlier releases of the RHEL4
postgres RPMs --- if you tried to run the initdb with SELinux
enforcement enabled, a lot of the init steps fail silently, and
you end up with no pg_user view, nor several other important things.

Stand-alone backend with -O command-line option.
As soon as you are able to dump your data, I'd recommend redoing
initdb with SELinux off (or update to a newer RPM which works around
the problem, then initdb).
