How to get total count of queries hitting DB per day or per hour?

["Sheena, Prabhjot" <Prabhjot.Singh@xxxxxxxxxxxxxx>]

Guys

              Is there a way to get total count of queries hitting Postgresql DB(verison 9.3) per day or per hour ? I cannot turn on log_statement=all coz that’s too much logging for our log file to handle. Is there another way to do that.

 

 

Thanks
