title: Safari history.db history_tombstones
body: <p>In Safari, my top hits keeps posting results to a page that I've deleted from my cache quite a long time ago. However, if I open the history.db in <code>SQlite</code> I see a number of tables including a "<em>history_tombstones"</em>. In this <em>history_tombstones</em> I see the link to the site that has been deleted from my cache. What is the table <em>history_tombstones</em> used for and how is it populated with entries? </p>
  
  <p>Bonus question is how do I permanently remove these entries? Deleting history.db and <em>history.db-wal</em> from my Mac only temporarily deletes these items as the entire DB reappears in minutes. Modifying the table directly doesn't do anything as the cells are overwritten with the original data.</p>
