    src/backend/optimizer/prep: prepunion.c

Log message:
    Quick hack to fix Oliver Elphick's problem with subselects in an
    inheritance query: make duplicate copies of subplans in adjust_inherited_attrs.
    When we redesign querytrees we really gotta do something about this
    issue of whether querytrees are read-only and can share substructure
    or not.
