Hello Admin team, I am new to Postgres and please excuse me if these are silly questions: 1. What is a worker process exactly in Postgres? 2. is max_parallel_workers specific to a session or instance. My max_parallel_workers is set to 8. If it is specific to instance, does it mean at any point of time I can only see 8 parallel processes despite the number of transactions in the db? 3. Does number of worker process have anything to do with active connections to the database. I have read the documentation but unable to catch up correctly. Any help from you is appreciated. Thanks, J. Teja.
