Connector failing when using DB Wrapper


I get the following error when using the DB Wrappers with Postgresql database:
Fatal error : Uncaught Exception: DB class not found: Postgres in D:\Apache\htdocs\connector\codebase\base_connector.php:343 Stack trace: #0 D:\Apache\htdocs\apps\metadata\baseconn.php(6): Connector->__construct(Resource id #3, ‘Postgres’) #1 {main} thrown in D:\Apache\htdocs\connector\codebase\base_connector.php on line 343

My code is as given as an image attachment:

Tell me where I have gone wrong.



Please, try to include the ‘db_postgre’ extension after the ‘base_connector’
