Hey,
So I ran across this today:
CREATE OR REPLACE FUNCTION RETURN_LOTS(INT) RETURNS SETOF INT AS $$ SELECT generate_series(1,$1); $$
COST 0.5 ROWS 50 SET work_mem TO '5MB' LANGUAGE 'SQL';
postgres=# explain analyze select return_lots(10000000);
QUERY PLAN
-----------------------------------------------------------------------------------------------Result (cost=0.00..0.26
rows=1width=0) (actual time=0.059..21411.187
rows=10000000 loops=1)Total runtime: 25951.904 ms
Shouldn't the estimated rows be 50?
