A complete restore of /var/lib/pgsql/data/ should have worked, if the
dump was taken while the database was idle. If you try to restore
selectively it will likely not work --- pg_log has to be in sync with
all of the data files. A filesystem dump of an active database is
unlikely to yield consistent results either.
