or only RAISE LEVEL SQLSTATE(text_expr)|text_expr [, ...]
if I use registered sqlstate, plpgsql knows text message. But I think this
syntax has more questions than exception's variables. It's really problem
declare one exceptio's variable? It's similar like using constant
variables or magic values.

DECLARE not_money EXCEPTION=SQLSTATE('U1101');
BEGIN
IF account < 0 THEN
RAISE EXCEPTION not_money;
...
or
BEGIN
IF account < 0 THEN
RAISE SQLSTATE ('U1101') 'Not money';
