Ad hoc SETOF type definition? - Mailing list pgsql-general

Pg 9.6.24 (Yes, I know it's EOL.)

This simple "programming example" function works perfectly. However, it 
requires me to create the TYPE "foo".

CREATE TYPE foo AS (tab_name TEXT, num_pages INT);
CREATE FUNCTION dba.blarge()
     RETURNS SETOF foo
     LANGUAGE plpgsql
     AS
$$
     DECLARE
         ret foo;
         bar CURSOR FOR
             select relname::text as table_name, relpages
             from pg_class where relkind = 'r'
             order by 1;
     BEGIN
         FOR i IN bar LOOP
             SELECT i.table_name, i.relpages INTO ret;
             RETURN NEXT ret;
         END LOOP;
     END;
$$;

Is there a way to define the SETOF record on the fly, like you do with 
RETURNS TABLE (f1 type1, f2 type2)?
