Confirmed here.

The error message is:

alvherre=# SELECT * from test where (str1, str2, id) > ('a', '1', 0);
ERREUR:  could not find member 4(25,25) of opfamily 426

Note that if I change the order of columns, it works:

alvherre=# SELECT * from test where (id,str1, str2) > (0,'a', '1');
 id | str1 | str2
----+------+------
  1 | a    | 1
  2 | b    | 2
