Modified files:
    src/backend/optimizer/prep: prepunion.c

Log message:
    Fix brokenness of nested EXCEPT/INTERSECT queries.  prepunion was being
    a tad sloppy about generating the targetlist for some nodes, by generating
    a tlist entry that claimed to be a constant when the value wasn't actually
    constant.  This caused setrefs.c to do the wrong thing later on.
