I would rather get rid of this %X/%X notation.  I know we have all grown
to like it, but it's always been a workaround.  We're now making the
move to simplify this whole business by saying, the WAL location is an
unsigned 64-bit number -- which everyone can understand -- but then why
is it printed in some funny format?
