What I would recommend as a first step is to stop the postmaster and
then take a tarball backup of the entire $PGDATA tree. This will at
least provide a chance to go back if subsequent tries mess things up
completely.
After that, I'd try a plain VACUUM (not FULL, not FREEZE) of pg_class
and see if that restores the missing tables to view in pg_tables.
If it does, go ahead and do a database-wide plain VACUUM, and you
should be OK. If it doesn't, we'll need to think of another plan.
