BTW, we don't need to recommend the heapallindexed option in the
release notes. Calling bt_check_index() will reliably indicate that
corruption is present when called against existing interval_ops
indexes once your fix is in. Simply having an index whose metapage's
allequalimage field is spuriously set to true will be recognized as
corruption right away. Obviously, this will be no less true with an
existing interval_ops index that happens to be completely empty.
