title: How to get a DataBase Design for POSTGRESQL to create a ER-Diagram?
body: <p>I am using <strong>postgresql 9.2</strong> </p>
  
  <pre><code>postgres=# select version();
                             version
  -------------------------------------------------------------
   PostgreSQL 9.2.4, compiled by Visual C++ build 1600, 64-bit
  (1 row)
  </code></pre>
  
  <p>and <strong>pgadmin III</strong></p>
  
  <p>I have a database with tables which have one-to-many &amp; many-to-one relationships.</p>
  
  <p>I want to make ER diagrams, i.e., a database design of the tables.</p>
  
  <p>I have searched and referred to <a href="https://stackoverflow.com/questions/9692913/">this question</a> but I am unable to understand what I should do to get the database design installed into my pgadmin III as shown in the video of the link, i.e., the <a href="http://s14.postimg.org/4b2m0ye7l/database.png" rel="nofollow noreferrer">image view</a>.</p>
  
  <p>I'm confused whether to make any installations, or is it like an Addon? I'm confused about what to do.</p>
  
  <p>I need some support on how to make this work so that I can make an ER-diagram by using pgadmin III.</p>
