Of course, but does it make sense for you to pay the ~ 5%/day performance penalty for the ~0.5%/year chance of having your system crush?
Unless your FreeBSD server is stuffed with exotic gamer hardware, i don't see the likehood of crush getting larger than that.

There's a difference in the file system integrity and the DB integrity. PG will keep the DB integrity just fine without the file system journaling. The journaling just makes recovery from crash that much faster. ie, running fsck on 6TB of disk storage takes a LONG time, sometimes hours, but with the journal enabled, it takes a few seconds.
