I believe the geeky non-helpful answer is to attach to the process with
gdb and do p debug_query_string which I believe will show you said long
running query. (Someone who actually hacks C can correct me on that, but
I believe I've done it that way before).  

Of course that idea lead me to wondering why we couldn't have a function
that could look at a connection (well, either by way of pid or possibly
transaction id) and show the current query being executed.
