Right now, it feels a bit incomplete. If it's not much work, I recommend breaking out the CREATE_REPLICATION_SLOT changes and updating pg_recvlogical, so that it can go in v14 (and pg_create_logical_replication_slot() will match CREATE_REPLICATION_SLOT). But if that's complicated or controversial, then I'm fine waiting for the other work to complete. Regards, Jeff Davis
