Connecting over UNIX domain sockets

I would like to have the option to connect to the database over UNIX
domain sockets (sidestepping the question of password management).

Even though the JVM knows about UNIX domain sockets, this
functionality is not exposed to user code, so we'd have to add some
JNI code.  Would you like to integrate this in some way?  If yes,
would you prefer a socket-based or libpq-based approach?
