It's also failing in the buildfarm, eg

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=conchuela&dt=2022-07-28%2020%3A57%3A50

Looks like only conchuela so far, reinforcing the idea that we're
only seeing it on FreeBSD.  I'd tentatively bet on a timing problem
that requires some FreeBSD scheduling quirk to manifest; we've seen
such quirks before.
