I overlooked the check for MCV in the logic building query

I'm not sure whether we should do back patch or not. However, I'll
add the check on the next patch because it is useful if you decide to
do the back patch on PG10, 11, 12, and 13.
BTW perhaps a quick look at the other \d commands would show if there are
precedents. I didn't have time for that.
Yes, we do promise that new psql works with older servers.
Yeah, makes sense. That means we need add the check for 12 / MCV.
I think we would not backpatch any of this, though.
I wasn't really planning to backpatch any of this, of course.
