That's pretty similar to health checking. The only difference is, we
would want a new knob which disable shutdown/backend termination
message.  That's an idea to worth to discuss but we already have tons
of tasks toward pgpool-II 3.5 and I'm not sure if it could be part of
3.5 release unless someone comes up with acceptable patches.
