Unless someone has a better idea, I suggest we just raise the timeouts
used in prepared_xacts from 1 sec to 2 sec. That should reduce the
recurrence rate to something vanishingly small if the problem is just
"it's too slow". If it's that something's actually getting stuck, then
we'll continue to see failures and will know that closer investigation
is needed.
