Well whenever I see:
select * from test where id=$var
I think "possible SQL injection".
I'd rather see bind variables be used or something similar, and when you
use those, the quotes are automatic.
With your method if the table is altered to int4 or something else, it
won't use the index (unless a postgresql dev adds stuff).
'456'::int8 seems to work too. But I suppose that's a Postgresql-ism.
