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.
