Base de données relationnelle

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.
