Certainly the easier path code wise :-) Being the belt, suspenders and steel tip boots (foot gun protection) type that I am, I would make a backup even if pg_upgrade copies all the data files. Having pg_upgrade copy the data files give you an extra layer of protection if desired, and can possibly save an admin who fails to get a good backup of the old PGDATA for what ever reason. ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
