could not find driver (ZF2 + Doctrine 2 + PostgreSQL). Wrong driver - database

Question

application.config.php :
'doctrine' => array(
'connection' => array(
// default connection name
'orm_default' => array(
'driverClass' => 'Doctrine\DBAL\Driver\PDOPgSql\Driver',
'params' => array(
'driver' => 'pdo_pgsql',
'host' => 'localhost',
'port' => '5432',
'user' => 'postgres',
'password' => 'root',
'dbname' => 'thebasee',
)
)
),
'driver' => array(
__NAMESPACE__ . '_driver' => array(
'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
'cache' => 'array',
'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Entity')
),
'orm_default' => array(
'drivers' => array(
__NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_driver'
)
)
)
),
module.config.php:
// Controllers in this module
'controller' => array(
'classes' => array(
'Account/Account' => 'Account\Controller\AccountController'
),
),
'doctrine' => array(
'driver' => array(
'orm_driver' => array(
'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
'cache' => 'array',
'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Entity')
),
'orm_default' => array(
'drivers' => array(
__NAMESPACE__ . '\Entity' => 'orm_driver'
)
),
'odm_driver' => array(
'class' => 'Doctrine\ODM\MongoDB\Mapping\Driver\AnnotationDriver',
'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Document')
),
'odm_default' => array(
'drivers' => array(
__NAMESPACE__ . '\Document' => 'odm_driver'
)
)
)
),
// Routes for this module
'router' => array(
'routes' => array(
'Account' => array(
'type' => 'segment',
'options' => array(
'route' => '/account[/:action][/:id]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Account/Account',
'action' => 'index',
),
),
),
),
),
// View setup for this module
'view_manager' => array(
'template_path_stack' => array(
'Account' => __DIR__ . '/../view',
),
),
Now, the error is:
"could not find driver" in /var/www/applicationDir/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:36
Driver for postgresql is installed (another project's works fine) but for MySql inst, and in track i sow this:
/var/www/applicationDir/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php(36):
PDO->__construct('mysql:host=loca...', 'postgres', 'root', Array)
It seems it uses Mysql driver, but why, if i choose Pg?!
Please help.
