Log message:
    Constant expressions that appear in ORDER BY, GROUP BY, DISTINCT ON
    lists should be reverse-compiled into targetlist index numbers, because
    that's the only interpretation the parser allows for a constant in these
    clauses.  (Ergo, the only way they could have gotten into the list in
    the first place is to have come from the targetlist; so this should always
    work.)  Per problem report from Peter E.
