C functions have always been able to return sets too; you don't honestly
think that a SQL function can do something a C function can't, do you?

There are really two independent improvements here: one is the ability
for plpgsql functions to return sets, and the other is a group of
improvements that make it easier to use a function-returning-set,
independently of what language it's written in.
