title: How does 'max_length' affect Django models?
body: <p>Does <code>max_length</code> affect anything outside of the maximum number of characters you can add to a specific database field (i.e. does it affect the amount of memory that is set aside for the database?).</p>
  
  <p>Would there be any unintended consequences for setting all fields to the maximum <code>CharField</code> length, which is ~65,000, even if it was completely unnecessary (apart from being bad practice)?</p>
