title: Import a csv with foreignkeys
body: <p>Let's say I have 2 tables: Students and Groups.</p>
  <ul>
  <li>The Group table has 2 columns: id, GroupName</li>
  <li>The Student table has 3 columns: id, StudentName and GroupID</li>
  <li>The GroupID is a foreign key to a Group field.</li>
  </ul>
  <p>I need to import the Students table from a CSV, but in my CSV instead of the Group id appears the name of the group. How can I import it with pgAdmin without modifying the csv?</p>
