There is a function which returns fd of the connection to postgresql database.
If you install a SIGPIPE handler on that connections, perhaps you can catch the
signal that backend is killed. But you will get that signal only when you
attempt to write to the  fd, according to 'man 7 signal' on my mandrake box.

Just theory. Try it out and let us know if it works..
