title: Do I need to reindex after vacuum full on Postgres 9.4
body: <p>I am using Postgres 9.4.</p>
  
  <p>I just ran vacuum full. I read about the differences between vacuum and vacuum full and considered a lot if I should run vacuum or vacuum full. As far as I can say, I required vacuum full and my db size came down from 48 GB to 24 GB.</p>
  
  <p>Would the old indexes would have become obsolete after vacuum full and do I need to run reindex?</p>
  
  <p>I ran "vacuum full verbose analyze", so analyze is done along with vacuum full.</p>
  
  <p>I read at several places that for Postgres > 9.0, I don't need reindex after vacuum full, but I want to be sure that it is the case.</p>
