Log message:
    simplify_function() mustn't try to evaluate functions that return
    composite types, because TupleTableSlots aren't Datums and can't be
    stored in Const nodes.  We can remove this restriction if we ever
    adopt a cleaner runtime representation for whole-tuple results, but
    at the moment it's broken.  Per example from Thomas Hallgren.
