You aren't going to be able to do that, because of the conflict with the
array type for it.

It might work to rename the array type out of the way --- I think that
in all PG releases where we have array of composite, the underscore
prefix is only a convention and not the hard-wired way of finding
the array type for a given element type.

There is some code in there to rename array types out of the way
automatically, but I think it only works during CREATE not RENAME.
