Very little, as it makes unjustifiable assumptions about all the
datatype's support functions being predictably propertied. (There's
more than one possible signature, let alone any secondary properties
such as volatility or other stuff we might think of in future.)
I think it'd be unworkable from pg_dump's point of view, as well.
