Hmm, would it be possible to use another signal for "cancel the current
query and enter a state where no queries are accepted"?  That would mean
driving the backend to a known idle state, allowing further action to
end the connection.  From the client perspective, the connection is no
longer useful anyway, so he can only disconnect.
