Is it possible to construct and return an array with plpgsql <br /><br /> like..<br /><br /> CREATE FUNCTION

RETURN(return_array);<br /> END;'<br /> LANGUAGE 'plpgsql';<br /><br /> I get the following error when I try to run
it:<br/> ERROR: parse error at or near "[" on line 4.<br /><br /> If this worked I could clean up a LOT of hacky

Simplified example:
CREATE FUNCTION test_array (INT[] )
RETURNS INT AS '
DECLARE id_array ALIAS for $1;count_it INT;
BEGIN
count_it := 1;
WHILE id_array[count_it] LOOPcount_it := count_it + 1;
END LOOP;
RETURN (count_it - 1);
END;'
LANGUAGE 'plpgsql';
returns the number of elements in the supplied array.

TIP 2: you can get off all lists at once with the unregister command
