Then, I'm probably using the wrong term. Right now, I have
max_worker_processes set to 16. What happens when query #17
wants some work done? What do you call the thing that handles
that? What is its algorithm for allocating work to the processes?
Or am I completely misunderstanding the role worker processes
play in execution?
