May I ask why? These messages are legitimately different; they're tunneled through CopyData, so their reservations don't collide with the top-level codes. > There's also backups, which use the replication protocol but > have their own special characters [0]. If we're going the prefix route, > would we add another prefix for those, or use the replication one? My vote would be to add another. 'p' is a password message in the top-level protocol (one of many, actually), a progress message in a backup stream, and a status request in a replication stream, so I think they deserve their own namespaces. --Jacob
