The patch looks good to me, too.

At first, I just wondered whether vacuumdb --missing-stats-only would work
on older servers, since the patch adds access to the attgenerated column,
which might not exist there. But that's not an issue, because
--missing-stats-only is supported only on servers version 15 or later,
where attgenerated is available.
