Noah Misch d024160fff Fix StatisticsObjIsVisibleExt() for pg_temp. 
Neighbor get_statistics_object_oid() ignores objects in pg_temp, as has
been the standard for non-relation, non-type namespace searches since
CVE-2007-2138.  Hence, most operations that name a statistics object
correctly decline to map an unqualified name to a statistics object in
pg_temp.  StatisticsObjIsVisibleExt() did not.  Consequently,
pg_statistics_obj_is_visible() wrongly returned true for such objects,
psql \dX wrongly listed them, and getObjectDescription()-based ereport()
and pg_describe_object() wrongly omitted namespace qualification.  Any
malfunction beyond that would depend on how a human or application acts
on those wrong indications.  Commit
d99d58cdc8 introduced this.  Back-patch to
v13 (all supported versions).
