While this is nice, it will not help you if the restoration directory is
different from your archive directory. That is : restore_command in
recovery.conf fetches from somewhere other than where archive_command in
postgresql.conf copied.
I am not sure how likely this situation is, but setting up log shipping,
or maybe recovering from disk failure *might* mean you need to bring the
saved archive files "back from somewhere else".
