title: Wordpress permalink names are saved somewhere and I want to clear them out
body: <p>I'm taking over a wp site that was not completed.  All the pages that had been created were deleted. </p>
  
  <p>I created a page and tried to rename its permalink to 'volunteer'.  </p>
  
  <p>However, I SUSPECT this page was once created because when I edit it and name it to /volunteer ... it automatically saves it as /volunteer-2 ?  </p>
  
  <p>IF I create a random named page ..i.e. testingPage, it will save the permalink like that just fine. </p>
  
  <p>(My permalinks setting is set to: /%postname%/) ...</p>
  
  <p>SO I am pretty sure there is a list somewhere of previously saved page names... can someone tell me where thats at and how I can clear it?</p>
