title: PGAdmin gets estimated row count from where?
body: <p>I noticed that the estimated row count isn't updated after removing some rows from the table.</p>

  <p>So, I ran <code>VACUUM ANALYZE</code> on the table, but it didn't work either.<br> Where is the place PGAdmin takes this value from? Does the <strong><em>query planner</em></strong> take the estimated row count from the same place?</p>
