Reset relhassubclass upon attaching table as a partition
We don't allow inheritance parents as partitions, and have checks to
prevent this; but if a table _was_ in the past an inheritance parents
and all their children are removed, the pg_class.relhassubclass flag
may remain set, which confuses the partition pruning code (most
obviously, it results in an assertion failure; in production builds it
may be worse.)
Fix by resetting relhassubclass on attach.
Backpatch to all supported versions.
