title: Generate N Records
body: <p>Is there a faster way to do something like this? Maybe using <code>generate_series</code>?</p>
  <pre><code>INSERT INTO users (email)
  VALUES
    ('user1@domain.com'),
    ('user2@domain.com'),
    ('user3@domain.com')
  </code></pre>
  <p>Is it possible to also easily add a relation for a profile?</p>
  <pre><code>INSERT INTO profiles (user_id)
  SELECT id FROM users WHERE email='user1@domain.com'
  
  INSERT INTO profiles (user_id)
  SELECT id FROM users WHERE email='user2@domain.com'
  
  INSERT INTO profiles (user_id)
  SELECT id FROM users WHERE email='user3@domain.com'
  </code></pre>
