title: Postgres pg_toast in autovacuum - which table?
body: <p>I have an autovacuum process running on pg_toast:</p>
  
  <pre><code>select query, from pg_stat_activity where query like '%autov%';
  "autovacuum: VACUUM pg_toast.pg_toast_15404513 "
  </code></pre>
  
  <p>How do I find out what table/index/whatever this pg_toast pertains to? Or is the autovacuum working on something else?</p>
