Log message:
    Repair for bug #691 --- CREATE TABLE AS column aliases fail to be
    applied when the select is a UNION (or other set-operation).

    An alternative route to a fix would be to leave analyze.c alone and
    change plan_set_operations in prepunion.c to take column names from
    the topmost targetlist.  But I am not sure that would work in all
    cases.  This patch seems the minimum-risk fix.
