This would require another (not syscached) pg_ relation plus support in heap access and some other parts. And it would be a DEFINITELY NOT indexable type. Also it would be subject to get removed someday after we implemented large tuples. But it would drop the pressure from the large tuple item close to zero IMHO. So if I can implement it in a way, that ensures it is easily removable again, why not?
