Right, that version number exists mostly for the benefit of pg_controldata
and allied utilities.  You would get a CRC failure in any case when trying
to go between inconsistent notions of what pg_control contains, but the
version number is supposed to help you figure out why that happened.
As things stand, though, it'd only mislead you.
