Where/how does one set this? In postgresql.conf or on the file system
or during compilation of postgres? I'm on FreeBSD 4.8 still.
I've got a box right now on which I'm comparing the speed merits of
hardware RAID10, RAID5, and RAID50 using a filesystem benchmark
utility (bonnie++). If I have time I'm gonna try different striping
block sizes. Right now I'm using 32k byte stripe size.
