Fujii, Simon,
For 9.1, both master and replica in a sync replication relationship are
required to be fsync'ing to disk. I understand why we had to do that
for our first cut at synch rep. Do you think, though, that it might
become possible to replicate without synch-to-disk for 9.2?
The use case I have is cloud hosting, where I'd rather have two or three
synchronous standbys than synch to disk.
