-- In Postgres 8.0.0 generate_series() is a built-in function
CREATE OR REPLACE FUNCTION generate_series(int, int) RETURNS setof int AS ' BEGIN  FOR i IN $1..$2 LOOP   RETURN NEXT
i; END LOOP;  RETURN; END;
 
' LANGUAGE plpgsql;

select '2004/12/01'::date + f1 from generate_series(0, 19) as t(f1);  ?column?
------------ 2004-12-01 2004-12-02 2004-12-03 2004-12-04 2004-12-05 [...] 2004-12-20
