SELECT INTO an array

Hi!

I'm trying to write a PLPGSQL Function using an array as an internal variable, but I don't seem to succeed:

CREATE FUNCTION ... RETURNS ... AS '
DECLARE
l_record integer[2];
BEGIN
SELECT INTO l_record col01, col02 FROM table01 WHERE ...;

when calling the function, I get a

ERROR: array_in: Need to specify dimension

How do I specify such dimension?

Thanks
Alberto
