I was just writing a syntical example and wanted to make sure it worked.
I found this:
CREATE OR REPLACE FUNCTION RETURN_LOTS(INT) RETURNS SETOF INT AS
$$
SELECT generate_series(1,$1);
$$ COST 0.5 ROWS 1000 SET work_mem TO '5MB' LANGUAGE 'SQL';
postgres=# explain analyze

This is repeatable. I expect a little regression because we have to
compile the SQL but 14 seconds?
generate_series is a quite efficient C function. I think it's pretty
damn good that the overhead of a SQL function on top of that is only 2X.
