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
