Ah --- that explains why I couldn't see a problem.
I've pushed 0001+0002 plus some followup work to fix other places
that could usefully use TimestampDifferenceMilliseconds(). I have
not done anything with 0003 (the TAP test for pg_prewarm), and will
leave that to the judgment of somebody who's worked with pg_prewarm
before. To me it looks like it's not really testing things very
carefully at all; on the other hand, we have exactly zero test
coverage of that module today, so maybe something is better than
nothing.
