Given that we don't need to write anything extra to WAL on upstream to support binary output, why not just have the request for binary data as an option for the pgoutput and have it chosen dynamically? Then it's the subscriber who asks for binary output via option(s) to START_REPLICATION. -- Petr Jelinek 2ndQuadrant - PostgreSQL Solutions https://www.2ndQuadrant.com/
