For most purposes, multiranges act like dependent objects of the associated range type: you can't create them separately or drop them separately. This is like the way that autogenerated array types behave. However, a couple of points were overlooked: array types automatically track the ownership of their base type, and array types do not have their own permissions but use those of the base type, while multiranges didn't emulate those behaviors. This is fairly broken, mainly because pg_dump doesn't think it needs to worry about multiranges as separate objects, and thus it fails to dump/restore ownership or permissions of multiranges. There's no apparent value in letting a multirange diverge from its parent's ownership or permissions, so let's make them act like arrays in these respects. However, we continue to let multiranges be renamed or moved to a different schema independently of their parent, since that doesn't break anything.
