Non-bugs

• No method to block effective_wal_level=logical when wal_level=replica is needed
  • the REPLICATION privilege already grants very powerful capabilities, including the ability to read all data via physical streaming and to hold back horizons. A user trusted with REPLICATION is already trusted enough that allowing them to create a logical slot does not represent a fundamentally new class of risk.
