I don't know what "Linux advanced server-4" means, but if it's RHEL4
and you've got SELinux enabled, this is a known problem with early
releases of the SELinux policy for Postgres --- some steps of the
initdb process fail due to permissions problems, leaving you with
missing system views and such. Get a more recent release. You
*definitely* need something more recent than 7.4.6 as far as Postgres
itself is concerned; we're up to 7.4.16 in that branch, not to mention
that 7.4.anything is old...
