Just looking at the committed diff, it seems painfully obvious that these
two messages were written by different people who weren't talking to each
other.  Why aren't they more alike?  Given

       pg_fatal("could not open version file \"%s\": %m\n", ver_filename);

(which seems fine to me), I think the second ought to be

       pg_fatal("could not parse version file \"%s\"\n", ver_filename);

The wording as it stands:

       pg_fatal("could not parse PG_VERSION file from \"%s\"\n", cluster->pgdata);

could be criticized on more grounds than just that it's pointlessly
different from the adjacent message: it doesn't follow the style guideline
about saying what each mentioned object is.  You could fix that maybe with
s/from/from directory/, but I think this construction is unfortunate and
overly verbose already.
