I noticed that the partially parallelized Merge Join EXPLAIN ANALYZE that you attach has a big misestimation: -> Merge Join (cost=3405052.45..3676948.66 rows=320 width=32) (actual time=21165.849..37814.551 rows=1357812 loops=4) Is this the best test case to show off the patch? This node is the immediate outer child of a Nested Loop Semi Join, and so I'm concerned that we measuring the wrong thing. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
