title: Postgresql 9.6 InitDB Fails
body: <p>Whenever I Try running the command below it always fails on RHEL7. I've tried on another similar OS (Newer) and it doesn't do this and just works.</p>
  
  <p>I'v looked into permissions of directories, disabled selinux (Just incase) and also looked into locales, however these settings match that of my other server.</p>
  
  <pre><code>/usr/pgsql-9.6/bin/postgresql96-setup initdb
  </code></pre>
  
  <p>Log output:</p>
  
  <pre><code>The database cluster will be initialized with locale "en_US.UTF-8".
  The default database encoding has accordingly been set to "UTF8".
  The default text search configuration will be set to "english".
  
  Data page checksums are disabled.
