If I try the following, I get the error:
=> select x(1);
NOTICE: Error occurred while executing PL/pgSQL function x
NOTICE: line 9 at return
ERROR: Attribute 'type_row_v' not found

So how do I generate a row that can be used as a parameter to a
function?
thanks

CREATE OR REPLACE FUNCTION x(
BIGINT
)
RETURNS BIGINT AS '
DECLARE
type_id_p ALIAS FOR $1;
type_row_v type%ROWTYPE;
BEGIN
SELECT * INTO type_row_v FROM type
WHERE type_id = type_id_p;

RETURN xy(type_row_v);
END;
' LANGUAGE 'plpgsql' WITH (isstrict);

CREATE OR REPLACE FUNCTION xy(
type
)
RETURNS BIGINT AS '
DECLARE
type_row_p ALIAS FOR $1;
BEGIN

IF type_row_p.type_id IS NULL THEN
RETURN -2;
END IF;

RETURN type_row_p.type_kind;
END;
' LANGUAGE 'plpgsql' WITH (isstrict);
