Well, we clearly need to fix GetOldestSnapshot so it won't crash,
but I do not think that having RETURNING queries randomly returning
"ERROR: no known snapshots" is acceptable even for a beta release.
If we aren't prepared to do something about that before Monday,
I think we need to revert 3e2f3c2e until we do have a fix for it.
What I suggested just now in <2850.1470592623@sss.pgh.pa.us> might
be implementable with a couple hours' work, though. Do you have a
reason to think it'd be insufficient?
