Works for me:

postgres=# do $$
begin
   insert into example values ('2001-01-01', 'foo', 'bar');
   insert into example values ('2001-01-01', 'foo', 'bar');
exception
   when others then raise notice 'caught %', sqlstate;
end;
$$;
NOTICE:  caught 23505
DO

How exactly are you seeing the wrong status code? What client are you using?
