interval

How can i get time interval only in minutes or in seconds ?
For example i have '1 month 15 days' and i need these time in
minutes.

lockhart=# select extract(epoch from interval '1 month 15 days') / 60;
?column?
----------
64800
(1 row)

Oh...thanks one more question.

I create these function:

CREATE FUNCTION sum_revenue() RETURNS real AS '

DECLARE
call RECORD;

BEGIN
tmpsum := 0;
FOR call IN SELECT
country,(date_part('epoch), starttime - endtime)::float AS seconds ,type from calls where sub_acc = 4 LOOP
RETURN call.minutes;
END LOOP;
end;
' LANGUAGE 'plpgsql';

And in call.minutes i've got '0';

Why ? How can i retrive call.minutes ?

these RETURN only for debug.
