    Done. GroupClause now identifies the TLE by a number which is
    placed into the Resdom by parser/rewriter.

    New  initdb  required  because  of  modifications   in   node
    print/read functions.

    Not   required   anymore   AFAICS.  Instead  I  modified  the
    targetlist  preprocessing  in  the  planner  so   that   junk
    attributes  used  by  group  clauses  get  added again to the
    expanded list.
