List pgsql-sql
maybe somthing like this:

CREATE OR REPLACE FUNCTION calendar (DATE, DATE) RETURNS SETOF DATE LANGUAGE 'plpgsql' AS '
DECLARE
    v_from ALIAS FOR $1;
    v_to ALIAS FOR $2;
    v_current DATE DEFAULT v_from;
BEGIN
    WHILE (v_current<=v_to) LOOP
        RETURN NEXT v_current;
        v_current:=v_current+1;
    END LOOP;
   
    RETURN;
END;
';

test it:
SELECT * FROM calendar('2005-01-01', '2005-01-31');
