title: PostgreSQL could not open file "base/xxxx/xxxxx" no such file or directory
body: <p>Recently I had a Hardware failure on my linux machine and after fixing hardware problem and bringing back my linux machine up, when I execute query against one of my table, following error is returned.</p>
  
  <pre><code>ERROR: could not open file "base/17085/281016": No such file or directory.
  </code></pre>
  
  <p>When checked in postgresql/base/17085 directory, file 281016 does not exist.</p>
  
  <p>Would the issue be resolved if I create file manually by using below commands? or is it a bad approach causing more troubles in future?</p>
  
  <pre><code>#touch 281016
  #chown postgres:postgres 281016
  #chmod 600 281016
  </code></pre>
