2) if archive_command is activated and working, the primary
server sends (preferably with rsync or some other "atomic tool") the
NEW WAL files to the standby server. Later, at some point, the primary
server will delete this files when considers that are not necessary
anymore.
Is 'scp' by itself considered an "atomic tool" for copying files to the
standby server? Does "atomic" mean that the program should copy a file
over using a temp file name and then renames at the end or does it mean
something else?
