  <p>What's the meaning of it and how can I hidden this message?</p>
  
  <p>My OS Version: MacOS-10.13.3 and vscode version:1.19.3</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I just found that message is from the extension <code>vscode-database</code>, but I still don't know what it means. Is anyone knows what it mean? Do I have to create a database configure file first ?</p>
