We also tried to port our patch for PG16, but the largest barrier was that a replication command ALTER_SLOT is not supported. Since the slot option two_phase can't be modified, it is difficult to skip decoding PREPARE command even when altering the option from true to false. IIUC, Adding a new feature (e.g., replication command) for minor updates is generally prohibited We must consider another approach for backpatching, but we do not have solutions for now.
