Tom,
Thanks.  I found out the key issue it. It's because the truncate command
can't have the "cascade".
For the other people reference. The right funcitons are :
***********************************************************
CREATE OR REPLACE FUNCTION truncate_t (IN tablename text)
RETURNS VOID
AS
$$
BEGIN
        EXECUTE 'TRUNCATE TABLE ' || quote_ident(tablename) || ';';
EXCEPTION
        WHEN undefined_table THEN
                RAISE EXCEPTION 'Table "%" does not exists', tablename;
END;
$$
LANGUAGE plpgsql SECURITY DEFINER STRICT;
***********************************************************
***********************************************************
CREATE OR REPLACE FUNCTION truncate_t (tablename text)
RETURNS VOID
AS
$$
BEGIN
        EXECUTE 'TRUNCATE TABLE ' || quote_ident(tablename) || ';';
EXCEPTION
        WHEN undefined_table THEN
                RAISE EXCEPTION 'Table "%" does not exists', tablename;
END;
$$
LANGUAGE plpgsql SECURITY DEFINER STRICT;
***********************************************************
usage : select truncate_t ('aaa');
Thanks everybody's help.
Regards.
Grace
