function install_verify_pdo() {
    // PDO was moved to PHP core in 5.2.0, but the old extension (targeting 5.0
    // and 5.1) is still available from PECL, and can still be built without
    // errors. To verify that the correct version is in use, we check the
    // PDO::ATTR_DEFAULT_FETCH_MODE constant, which is not available in the
    // PECL extension.
    return extension_loaded('pdo') && defined('PDO::ATTR_DEFAULT_FETCH_MODE');
