I can reproduce the exception by running test code when the driver is
loaded from the bootstrap classpath
('-Xbootclasspath/a:jars/postgresql.jar')

It seems reasonable to fall back to the system classloader if the driver
was loaded from the bootstrap classloader. I will commit a change to do
this shortly.
