Yeah, it seems likely that there is some additional triggering
condition that we don't understand; otherwise there would be more
people complaining than just you. But if updating to PG16 gets
rid of the problem, I'm not sure it is worth the time to try to
narrow down what that additional trigger is.

Of course, if you still see the issue after upgrading, we'll have
to dig harder.
