Your explanation is clear, however the name max_parallel_workers makes it sound like that parallelising an operation is all about workers. Yes it depends a lot on the number of workers allocated for parallel operation, but that is not everything. I think calling it max_parallelism as suggested by Alvaro upthread suits better than max_parallel_workers. With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
