Otherwise you need to reconfigure your drive to not cache writes. I forget the incantation for that but it's in the PG list archives.
There's a dicussion of this in the docs now, http://www.postgresql.org/docs/8.3/interactive/wal-reliability.html
hdparm -I lets you check if write caching is on, hdparm -W lets you toggle it off. That's for ATA disks; SCSI ones can use sdparm instead, but usually it's something you can adjust more permanently in the card configuration or BIOS instead for those.
