---------------------------------------------------------------------------

The JDBC driver requires

  permission java.net.SocketPermission "host:port", "connect";

in the policy file of the application using the JDBC driver
in the postgresql.jar file.  Since the Socket() call in the
driver is not protected by AccessController.doPrivileged() this
permission must also be granted to the entire application.
