This *should* be possible but I haven't tested it.
There is a code path on secondary checkpoints that indicates that crash
recovery can occur even when the database was shutdown, since the code
forces recovery whether it was or not. On that basis, this may work, but
is yet untested. I didn't mention this because it might interfere with
getting hot backup to work...
