JAVA(intelliJ idea) проблемы с установкой JDBC?

Развернул на localhost сервер + поставил базу postgreSQL. первая на 8080 вторая на 5432.

Закидывал в мавен такие депенденси:

<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.1-901-1.jdbc4</version>
</dependency>

и вот так тоже пробовал.

<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.4</version>
</dependency>

Суть в том, что при выполнении

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class BazaTest {
public BazaTest() throws SQLException, ClassNotFoundException {
Class.forName("org.postgresql.Driver");
Connection connection = null;
connection = DriverManager.getConnection(
"jdbc:postgresql://localhost:5432/postgres","username", "password");
connection.close();
}
}

Я получаю ошибку: Если есть Class.forname() - тогда то, что передал в этот метод. Если убираю, то not suitable driver for ***. Я так понимаю, что я не правильно подключаю как-то драва(.

P.S пробовал через Setting->Project Structure добавить сразу jar файлик с дравами - тоже провал.

Как дальше жить?

Вот оба стэка
