PHP致命错误：在第144行的system / database / DB.php中找不到类'CI_DB_postgre_driver' - CodeIgniter

Question

I'm working with CodeIgniter and when I try to connect to a PostgreSQL database with

$this->load->database();

it show me a blank page. In the Apache log, I see the following error:

PHP Fatal error: Class 'CI_DB_postgre_driver' not found in system/database/DB.php on line 144

autoload line: $autoload['libraries'] = array('database');

Here's my database.php:

$active_group = 'default'; $active_record = TRUE;

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'user';
$db['default']['password'] = 'user';
$db['default']['database'] = 'database';
$db['default']['dbdriver'] = 'postgre';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Check if you don't have eval() function disabled:

var_dump(ini_get('disable_functions'));
