Agreed. How about max_worker_processes = 8 as before, with
max_parallel_workers of maybe 6? Or just set them both to 8.
I'm not sure that the out-of-the-box configuration needs to
leave backend slots locked down for non-parallel worker processes.
Any such process would require manual configuration anyway no?
