I only skimmed that link, but afaict most of this can be done today in postgres, with a bit different syntax, using CTEs. Postgres implements this as an extension to the standard CTE syntax. WITH data_src AS (SELECT * FROM source_tbl), insert_a AS (INSERT INTO a SELECT * FROM data_src WHERE d < 5), insert_b AS (INSERT INTO b SELECT * FROM data_src WHERE d >= 5) INSERT INTO c SELECT * FROM data_src WHERE d < 5 It's a bit annoying that the last "arm" of the insert looks a bit difference. OTOH, it's a much more general syntax. Greetings, Andres Freund
