Hm, if that's as much as we have to touch, I think there's a good
argument for squeezing it into v12 rather than waiting. The point
here is mostly to avoid a behavior change from pre-v12, but if we
allow v12 to have a different behavior, it's questionable whether
we'd want v13 to change it back.
Just looking at the patch, I wonder whether it doesn't need some
server-version checks. At the very least this would break with
pre-9.1 servers, which lack COLLATE altogether.
