For modern PG versions on Linux, you basically shouldn't ever have to
touch those numbers. I'd only start to worry if I saw server startup
failures. These values do *not* constrain what you can set for
shared_buffers or the like; at most, they'd constrain how many PG
instances you can run on one machine.
