That would look like the way to go.
I made changes to the previous version, so that it avoids to resolve CTE name duplication. regression=# with t as (select 1 as i) insert into z with t as(select 2 as i )values ((select * from t)); INSERT 0 1 Time: 1.656 ms regression=# table z; f3 ---- 2 (1 row) Also, the sample Marko gave is OK. > CREATE TABLE foo(a int); > > WITH t AS (SELECT * FROM foo) > INSERT INTO bar > WITH RECURSIVE foo (SELECT 1 AS a) > SELECT * FROM t; > Hope this covers all the cases.
