Replication slot synchronization (sync_replication_slots = on) requires wal_level to be logical. This commit prevents the server from starting if sync_replication_slots is enabled but wal_level is set to minimal or replica. Failing early during startup helps users catch invalid configurations immediately, which is important because changing wal_level requires a server restart.
