Disallow starting server with insufficient wal_level for existing slot. Previously it was possible to create a slot, change wal_level, and restart, even if the new wal_level was insufficient for the slot. That's a problem for both logical and physical slots, because the necessary WAL records are not generated.
This removes a few tests in newer versions that, somewhat inexplicably, whether restarting with a too low wal_level worked (a buggy behaviour!). Reported-By: Joshua D.
