Actually, I think we could teach the PLs to do it - just not transparently, so we'd need to mark which functions used the new protocol. Such functions would get a state object as an implied first argument, so in plperl it might work like this (for a generate_series-like function):
To support this I think we'd need to do something like: create function mygs(int, int) returns setof int language plperl with srfstate as $$ ... $$;
