ISTM that I reviewed the initial patch.

AFAICR I agreed with the comment that whether it was appropriate to go on
was unclear, but it did not strike me as obviously a bad idea at the time,
so I let it pass. Now it does strike me as a bad idea (tm):-) My English
is kind of fuzzy, so I tend not to comment too much on English unless I'm
really sure that it is wrong.

Note that there is another 100% cpu pgbench bug, see
https://commitfest.postgresql.org/15/1292/, which seems more likely to
occur in the wild that this one, but there has been no review of the fix I
sent.
