Fix assertion failure with ALTER TABLE ATTACH PARTITION and indexes
Using ALTER TABLE ATTACH PARTITION causes an assertion failure when
attempting to work on a partitioned index, because partitioned indexes
cannot have partition bounds.
The grammar of ALTER TABLE ATTACH PARTITION requires partition bounds,
but not ALTER INDEX, so mixing ALTER TABLE with partitioned indexes is
confusing. Hence, on HEAD, prevent ALTER TABLE to attach a partition if
the relation involved is a partitioned index. On back-branches, as
applications may rely on the existing behavior, just remove the
culprit assertion.
