I am not able to set wal_sync_method to anything but fsync on FreeBSD 9.0
for a DB created on ZFS (I have not tested on UFS). Is that expected ? Has
it anything to do with running on EC2 ?

Can you explain what prevents you for setting the wal_sync_method?

I don't remember the exact error message, but basically, if I set it to
anything else but fsync, when I start PostgreSQL, it tells me that the new
method is not available on my platform.
