Using PDO for database connection

I'm trying to use PDO driver to access the database:
 my database config:

PHP Code:

public $default = [
        'DSN'      => 'pgsql:host=localhost;port=3306;dbname=cipm',//I add this based on documention
        'hostname' => 'localhost',
        'username' => 'root',
        'password' => '123',
        'database' => 'cipm',
        //'DBDriver' => 'MySQLi',
        'DBDriver' => 'PDO',
        'DBPrefix' => 'pr_',
        'pConnect' => false,
        'DBDebug'  => (ENVIRONMENT !== 'production'),
        'cacheOn'  => false,
        'cacheDir' => '',
        'charset'  => 'utf8',
        'DBCollat' => 'utf8mb4_general_ci',
        'swapPre'  => '',
        'encrypt'  => false,
        'compress' => false,
        'strictOn' => false,
        'failover' => [],
        'port'     => 3306,
    ]; 


error: 

Code:

Class '\CodeIgniter\Database\PDO\Connection' not found

Does CI 4.0.4 suppor PDO?

Do a search in the forums here for ( CodeIgniter supported database drivers ) I gave some other user the driver list for version 3 and 4 of CodeIgniter.

What did you Try? What did you Get? What did you Expect?

It looks these are not PDO support for Codeigniter 4. at least I didn't find anything!

Ya I just checked it's not in ver 4 yet, but I'm sure someone is working on it.
