What do you expect to happen? It's a JDBC driver, not a standalone
program. You can't run it with "java -jar". It goes on the classpath so
that Java programs can use it to connect to PostgreSQL.

How to add it to the classpath depends on the Java software you are
using. Check the manual for the software package you are attempting to
use. The PgJDBC manual gives generic instructions for Java programmers.
