If not, how I can suppress it? It is quite annoying, when I saw these message keep printing out from my c++ console. Those are informational messages. You can change what level of messages your application gets by changing the setting 'client_min_messages' either globally or in your C++ program. Apparently it's currently set to the 'notice' level or lower, you probably want to set that to 'warning' or maybe even higher.
