title: Anything similar to MySQL Proxy for PostgreSQL?
body: <p>I am looking for something similar to <a href="https://launchpad.net/mysql-proxy" rel="nofollow">MySQL Proxy</a>. The purpose is to modify incoming queries on the server. I am not looking for alternative ways to achieve the same. My best guess at the moment is to modify GridSQL, but this adds complexity and it takes time. I have asked this question before in a vastly different way and got no relevant results, so I deleted that question and added this one.</p>
  
  <p>Edit: It is important that the client can continue to utilize the PostgreSQL protocol, so the package I am looking for needs to communicate using it.</p>
