title: Where is the postgresql wal located? How can I specify a different path?
body: <p>I want to create a database with the data files and the wal on different filesystems. I want the wal on a separate server over NFS, to avoid a loss of data in case of a fs/disk crash.</p>
  
  <p>Where is the wal written?</p>
  
  <p>Can I force it to a different location than the default via the configuration?</p>
  
  <p>I'm on 9.1 if that matters.</p>
  
  <p>Thanks.</p>
