title: Postgres Update - version mismatch error when running commands
body: <p>I recently updated Postgres from version 9.3 to 9.6.  After the update all of my commands (such as pg_dumpall) all point to version 9.3.  I get the error of version mismatch. </p>
  
  <p>I found that if I change my symlink in /usr/bin to point to 9.6 it seems to work.  Is there a better way to point my commands to version 9.6?  Thanks you for your help!</p>
