How to return seto records from seof record function? I tried pg_background extension:

 

CREATE OR REPLACE FUNCTION public.autonomous (p_script text)

RETURNS SETOF record

LANGUAGE plpgsql

VOLATILE STRICT PARALLEL UNSAFE

AS $autonomous$

DECLARE

l_id integer;

BEGIN

l_id := pg_background_launch(p_script);

RETURN QUERY SELECT * FROM pg_background_result(l_id) AS (r record);

END;

$autonomous$;

 

SELECT * FROM autonomous('SELECT now()') AS (a timestamptz);

 

SQL Error [42804]: ERROR: structure of query does not match function result type

  Detail: Returned type record does not match expected type timestamp with time zone in column 1.

  Where: SQL statement "SELECT * FROM pg_background_result(l_id) AS (r record)"

PL/pgSQL function autonomous(text) line 6 at RETURN QUERY
