I think that the type of your user is different from mine. If server fails
by simple termination of process, I don't want to spend 1min for
restarting other than catching up itself. For me, getting a fresh backup
(not only copying backup data but also checkpoint by pg_start_backup)
is expensive operation.

Of course, since I'm not planning to tackle that problem in 8.4,
I would not add "additional" synchronization point.
