Under FreeBSD 9, what filesystem should I use for PostgreSQL? (Dell 
PowerEdge 2900, 24G mem, 10x2T SATA2 disk, Intel RAID controller.)

  * ZFS is journaled, and it is more independent of the hardware. So if
    the computer goes wrong, I can move the zfs array to a different server.
  * UFS is not journaled. Also I have to rely on the RAID card to build
    the RAID array. If there is a hw problem with it, then I won't be
    able to recover the data easily.

I wonder if UFS has better performance or not. Or can you suggest 
another fs? Just of the PGDATA directory.
