If you do a filesystem level backup the only "safe" way to do this is to
either stop postgres and then backup, or if you are using a logical
volume manager take a snapshot. You cannot just "tar" a "live" pgdata
directory as the contents will change as tar goes through each file and
you'll be left with a corrupt database.
