Well, I think we could drop node, if you like. I think parallel wouldn't be good to drop, though, because it sounds like we want a global limit on parallel workers also, and that can't be just max_workers. So I think we should keep parallel in there for all of them, and have max_parallel_workers and max_parallel_workers_per_gather(_node). The reloption and the Path struct field can be parallel_workers rather than parallel_degree. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
