title: PostgreSQL connection issue
body: <p>I am new to PostgreSQL and I am trying to create a connection but I don't know for some reason my connection is not being established. </p>
  
  <p>At first it said that <code>cant hear the server</code> so whenever I go in to <code>task manager</code> and try to run Postgres servers it says "THE SYSTEM CAN NOT FIND THE FILE SPECIFIED" so I tried to remove Postgres completely from the system but it not completely uninstalling it from my laptop. I think its just remaining some instances in to my laptop which is not letting it to uninstall completely. </p>

  <p>I have attached the image above. Please see that. I have deleted every Postgress thing from my laptop but I think there is still some left in the laptop that is why it is showing this in the services.</p>
