The driver is not a selfcontained Java program and does not provide a
main class. Trying to run it with -jar will produce the above error. You
want to run with the driver jar in the classpath (e.g. via a -classpath
argument to your JVM) *in addition to* your own code, and specify your
own main class as the entry point.

Frankly, you may be better off looking for an introductory Java forum
for help. Understanding how the JVM locates classes and how to modify
your classpath is a prerequisite for using *any* sort of 3rd party
library; it's not specific to JDBC or PostgreSQL.
