Tom Lane 7418767f11 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.)
