That doesn't follow. That just means you can't implement a unix domain socket
driver using only Java. Is there some reason the driver has to be pure a Java
driver?

I had always assumed the JDBC driver isn't currently pure java and is just an
API wrapper around libpq. Writing and maintaining a pure java driver would be
much more work and be much slower for no practical gain.
