That was a possible design, but that's not will be there for this
release.
I opposed adding the "we do the base backup for you" feature because
there are many ways of doing a base backup and it would likely have
restricted your options to do so. One issue that would cause is limiting
the speed of the base backup to a single libpq connection, which would
cause performance problems. So yes, super-simple, but not super-good for
many big users.
