title: How to find database name of \data\base postgres folders?
body: <p>I have a large folder of 70 GB in my postgres installation under:</p>
  
  <p><code>D:\Program Files\PostgreSQL\9.5\data\base\130205</code></p>
  
  <p>Question: how could I find out which database is based on that folder?
  I have like 10 databases running on the same server, and most of them having a tablespace on a different drive. </p>
  
  <p>But probably I'm missing a mapping somewhere, maybe a large index or kind of. How can I find out the "causing" database of these amounts of data?</p>
