jdbc tcpKeepAlive parameter

the documentation is a little skimpy on the operation of tcpKeepAlive...

we've got a scenario where the java client applications sometimes abort
without cleaning up, and leave a postgres server process just sitting
there.     I'm assuming tcpKeepAlive=true would cause these processes to
timeout eventually and clean themselves up?   Is this a 2-way keepalive,
in that if the server process dies, the client connection would timeout,
too?

on libpq, there's some options for the keepalive interval and count, but
I don't see any such in JDBC?
