‘B’ means a backend and ‘F’ means a frontend. Maybe as [1] does, we should add the note like "Each is marked to indicate that it can be sent by a frontend (F) and a backend (B)" into the description about each message format for START_REPLICATION.

Maybe we should move the "protocol message formats” before “stream replication protocol” or referenced it in "stream replication protocol”. -- Best regards Japin Li
