See the discussion of the NegotiateProtocolVersion message which has been around for a long time but is still not supported by all clients. https://www.postgresql.org/docs/current/protocol.html https://www.postgresql.org/docs/current/protocol-message-formats.html No changes to the format of that message are proposed. The startup message also contains a version number, and changes the format of that message are also not proposed. -- Robert Haas EDB: http://www.enterprisedb.com
