Yes, but using restore_command is not terribly convenient. On
Linux/UNIX systems you have to enable ssh access, which is extremely
hard on Windows.
IMO Streaming replication is not yet easy enough to set up for
ordinary users. It is already proposed that making base backup easier
and I think it's good. Why don't we go step beyond a little bit more?

Did Fuji-san agreed on the conclusion?
