hello
try to wrap your query to subselect,
npcps_201=# select 1,2,2,3;?column? │ ?column? │ ?column? │ ?column?
──────────┼──────────┼──────────┼────────── 1 │ 2 │ 2 │ 3
(1 row)
Time: 0.171 ms
npcps_201=# select * from (select 1,2,2,3) x (a,b,c,d);a │ b │ c │ d
───┼───┼───┼───1 │ 2 │ 2 │ 3
(1 row)
Time: 0.202 ms
