PDO doesn't let you send multiple queries in the one request.

Since you're connecting to postgres, you can use this to do a bulk-insert:

http://www.php.net/manual/en/function.pg-put-line.php

Though it's not part of pdo, and also postgres 'copy from stdin' is all 
or nothing - so if you have one line of bad data in there, none of it's 
committed.
