Back in 2001, there was a lengthy thread on the PG Hackers list about PG
and journaling file systems
(http://archives.postgresql.org/pgsql-hackers/2001-05/msg00017.php), but
there was no decisive conclusion regarding what FS to use. At the time
the fly in the XFS ointment was that deletes were slow, but this was
improved with XFS 1.1.
I think a journaling a FS is needed for PG data since large DBs could
take hours to recover on a non-journaling FS, but what about WAL files?
