Modified files:
src/backend/optimizer/util: Tag: REL7_4_STABLE clauses.c

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.
