To further the case of the not-so-low-probability, we have customers
that are hitting this about once per day, with Postgres 14 ... so their
systems are crashing all the time :-( We've collected a bunch of
backtraces, and while I didn't analyze all of them, I hear that they all
look related to this fix.
