> Fix pgpool crash when pgpool child process exits.
> 
> When a pgpool child process exits, close_all_backend_connections() is
> called, which is responsible for closing all connections to backend in
> the connection pool. It used mistakenly MAIN_CONNECTION macro, which
> is fine for current active connections but is not good for pooled
> connections because a main node could be different at the time when
> the connection pool was created. Fix is using in_use_backend()
> instead.
