title: connect google spreadsheet to amazon redshift with jdbc mysql vs postgresql
body: <ul>
  <li><p>I have an amazon redshift db that supports connecting a postgresql client with jdbc</p></li>
  <li><p>google apps scripts support connecting to a db with jdbc, but only with the mysql, ms sql, and oracle protocol, but not postgresql.  If I try, not surprisingly I get error: </p></li>
  </ul>
  
  <p>'Connection URL uses an unsupported JDBC protocol.'</p>
  
  <p>Looking at some google forums, this has been an issue for several years with no response from google.</p>
  
  <p>Is there any workaround?  </p>
  
  <p>thanks</p>
