A simple scp leaves you vulnerable to a WAL file only being partially
copied if a backhoe hits at just the right moment. I believe that
wouldn't be an issue with rsync, since it won't put a file in place
until it's completely transfered. So if you want to use scp, I think
you'd need to scp to a temporary directory, and then do a final move.
