Hmm, I also see that at -O3 (not at -O2) when using Fedora 39's
gcc 13.2.1, but *not* when using RHEL8's gcc 8.5.0.
I'm not sure how excited I am about curing that, though, because gcc
13.2.1 spews several other totally baseless warnings (see attached).
Some of them match up with warnings we're seeing on buildfarm member
serinus, which I seem to recall that Andres had tracked to a known gcc
bug.
regards, tom lane
