title: metrics from the postgres_exporter
body: <p>I am working on postgres monitoring by referring to <a href="https://docs.sysdig.com/en/docs/sysdig-monitor/monitoring-integrations/application-integrations/postgresql/" rel="nofollow noreferrer">page</a>, and my postgres_exporter version is v0.8.0, and found some metrics missing, for example:</p>
  <ul>
  <li>pg_stat_user_tables_n_tup_hot_upd</li>
  <li>pg_stat_user_tables_idx_scan</li>
  <li>pg_stat_user_tables_seq_scan</li>
  </ul>
  <p>Is there anyone who uses these metrics? and what is the postgres_exporter version?
  Thank you.</p>
