But you'd have part of it too. Because then you'd have semantically independent parallel nodes in the plan that do some meaningful data wrangling and spit little output, whereas the previous plan did not do much with the data and spit loads of rows as a result. This is a big previous step for parallel execution really. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
