I use PDO_SQLite 5.1.1. This module is so useful.
But I'm problem about I can't execute "ATTACH DATABASE".
When I execute following snippet,I get following message.

And I couldn't find "db2"table in sqlite_master table.
Now, I think the function "ATTACH" is bugged or  unimplemented yet.

So..I'll feel happy if you would fix it :)

Reproduce code:
---------------
$pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$pdo->query("ATTACH DATABASE 'db2.sqlite3' AS db2;");
$stmt=$pdo->query('select * from db2.foo;');
while($result = $stmt->fetch(PDO::FETCH_ASSOC)){
  var_dump($result);
}


Expected result:
----------------
Output data about db2.foo.

Actual result:
--------------
string(64) "SQLSTATE[HY000]: General error: 1 no such table: db2.foo"
