One of my reasons for liking max_parallel_workers is that you can sensibly compare it to max_worker_processes to figure out how many workers you're likely to get. If you think in terms of "degree" it takes some additional mental arithmetic to understand what will happen. > Presumably the leader isn't counted towards max_parallel_workers?
