That should probably get committed as a separate bug fix, and
back-patched. Since HEAP_ONLY_TUPLE is 0x8000, the result of the existing
macro would actually fail to fit into a bool variable, meaning we have a
real coding hazard here. It would be nasty if code developed in HEAD
failed when back-patched because of that.
Andres ran around and fixed a bunch of these hazards before, but
evidently missed this one.
