title: postgreSQL dump file generated when exporting is blank
body: <p>I have a database named housing that I want to export. However, everytime i export it, it generates a blank dump file. I cannot identify what I've been doing wrong. Please help.</p>
  
  <p>I'm trying using phppgadmin, I clicked export, selected SQL, structure  and data as format and then download, but the dump file generated is always blank.</p>
  
  <p>I think I know now what the problem is, I have different two versions of postgreSQL installed on my laptop. postgreSQL version 9.3.6 that comes with Bitnami WAPPstack) and I forgot that I had previously installed postgreSQL version 9.4.1 too. I get a pg_dump aborting because of server version mismatch. How do I fix this? Can I just simply uninstall the one that is not with the Bitnami WAPPStack? Or will my database be deleted along with it? I'm sorry I know nothing . :(</p>
