It's been doing this in parallel queries, in v11 and up:

which looks like an external problem to me --- certainly, nothing
we changed yesterday would explain it. Did you change anything
about the system configuration, or do a software update?

I did do an upgrade to a later SVN rev.
Let me reboot and see if that fixes anything.
(this is -CURRENT on FreeBSD, so it's always a moving target).

Hi Larry,
I'm seeing this on my FreeBSD 13 bleeding edge system too (built a
couple of days ago) and will see if I can find out what's up with
that. The most obvious culprit is the stuff that just landed in the
kernel to support Linux-style memfd_create() and thereby changed
around some shm_open() related things. Seems to be clearly not a
PostgreSQL problem.
Thanks,
Thomas
