Yes I see it now (after some more digging about RAID 1). Looks like PostgresQL.org comes to the rescue again and explains: http://www.postgresql.org/docs/8.2/interactive/continuous-archiving.html So it looks like it should be a simple matter to configure this setup to archive WAL from the RAM disk to more permanent storage.
