Applications do not need to explicitly load the org.postgresql.Driver
class because the pgjdbc driver jar supports the Java Service Provider
mechanism. The driver will be loaded by the JVM when the application
connects to PostgreSQL™ (as long as the driver's jar file is on the
classpath).
### Note
Prior to Java 1.6, the driver had to be loaded by the application - either by calling
```java
Class.forName("org.postgresql.Driver");
```
or by passing the driver class name as a JVM parameter.
`java -Djdbc.drivers=org.postgresql.Driver example.ImageViewer`
These older methods of loading the driver are still supported but they are no longer necessary.
