Because "degree of parallelism" is standard terminology, I guess. Also, consider that we have the related but actually sorta different GUC max_worker_processes. I think max_parallel_workers to control the per-query behavior and max_worker_processes to control the global system behavior would be confusing - those names are very close together. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
