First time I'm hearing about that, but I'll admit that I am cheating
because -Wformat is forced in my local builds for some time now.  I'm
failing to see the issue with meson and ./configure even if I remove
the switch, though, using a recent version of gcc at 13.2.0, but
perhaps Debian does something underground.  Are there version and/or
environment requirements to be aware of?

Forcing -Wformat implies more stuff that can be disabled with
-Wno-format-contains-nul, -Wno-format-extra-args, and
-Wno-format-zero-length, but the thing is that we're usually very
conservative with such additions in the scripts.  See also
8b6f5f25102f, done, I guess, as an answer to this thread:
https://www.postgresql.org/message-id/4D431505.9010002%40dunslane.net

A quick look at the past history of pgsql-hackers does not mention
that as a problem, either, but I may have missed something.
