title: How to change the OpenERP column limit in tables?
body: <p>I have been working on <code>OpenERP-7</code> module development and I have come across a very strange issue when <code>adding new fields</code> to my model. It says that I have exceeded the <code>column limit</code> for the tables. Now I want to either change this limit or what? When I tried to reinstall after uninstalling the module, I am experiencing this issue : </p>
  
  <pre><code>OperationalError: tables can have at most 1600 columns
  </code></pre>
  
  <p>I have tried to remove the fields from my source code and updated the modules but still cant resolve it . I have come to know that there are certain columns in <strong>PostgreSQL</strong> which are hidden and we need to delete them to make things work.
  Hopes for suggestions .Thanks</p>
