title: Google Cloud PostgreSQL: Utilization remains at 100%
body: <p>I am using Google Cloud PostgreSQL which has utilization CPU 100%. I have upgraded the instance to use 2 cores. Now the instance is running on 2 CPU's and 3.75Gb of RAM. Still the instance is using 100% of CPU resources. Again, I have upgrade the instance to 6 cores and 12Gb of RAM, but still no change in CPU utilization. Here are some stats metrics:

  <p>I want any thought about why this is happening, how can I figure out the solution? 
  I have checked the number of queries running on PostgreSQL. Number of queries is less than 100 and execution time is less than 30 seconds. PostgreSQL verison is 9.6  </p>
