Thanks for the report! I usually always run a make check-world locally and also
launch the CI tests on my github repo before submitting patches. This time,
that was a one line change (as compared to v13), so confident enough I did not
trigger those tests. Murphy's Law I guess ;-)
So yeah, back to the issue, we have to pay more attention for the WAL stats
because pgWalUsage is "incremented" without any check with pgstat_tracks_backend_bktype()
(that's not the case for the IO stats where the counters are incremented taking
into account pgstat_tracks_backend_bktype()).
So for the moment, in the attached I "just" add a pgstat_tracks_backend_bktype()
check in pgstat_backend_have_pending_cb() but I'm not sure I like it that much...
Will think more about it...
