Most cluster-wide settings like this are named max_something
(max_connections, max_wal_senders, max_replication_slots), whereas
things that apply on a lower level are named max_something_per_something
(max_files_per_process, max_locks_per_transations).
So let's leave max_worker_processes mostly alone and not add any
_total_, _absolute_, _altogether_. ;-)
