title: Enable the query cache in postgreSQL to improve performance
body: <p>My application is very database intensive so I'm trying to reduce the load on the database. I am using PostgreSQL as rdbms and python is the programming language.</p>
  
  <p>To reduce the load I am already using a caching mechanism in the application. The caching type I used is a server cache, browser cache.</p>
  
  <p>Currently I'm tuning the PostgreSQL query cache to get it in line with the characteristics of queries being run on the server.</p>
  
  <p>Questions:</p>
  
  <ol>
  <li>Is it possible to fine tune query cache on a per database level?     </li>
  <li>Is it possible to fine tune query cache on a per table basis?</li>
  <li>please provide tutorial to learn query cache in PostgreSQL.</li>
  </ol>
