A complain that I have about such concepts is that it creates a dependency between utilities which are usually classified by distributions as client-side (pg_basebackup goes to postgresql-client for Debian), and the server itself. There is perhaps room for an extension though. If many vendors are providing such an option at SQL level, it would mean that there is demand for it. -- Michael
