In pg_dump, don't dump a stats object unless dumping underlying table. If the underlying table isn't being dumped, it's useless to dump an extended statistics object; it'll just cause errors at restore. We have always applied similar policies to, say, indexes.
(When and if we get cross-table stats objects, it might be profitable to think a little harder about what to do with them. But for now there seems no point in considering a stats object as anything but an appendage of its table.) Rian McGuire and Tom Lane, per report from Rian McGuire. Back-patch to supported branches.
