Maybe.  I'm a bit hesitant to add too many smarts to pg_rewind.  It's a tool
for when something has gone wrong with a cluster (albeit probably not at the
filesystem level), and at that point I feel it's better to put the user fully
in charge. Perhaps I'm overly cautious, curious to hear from others.
