title: Django Postgres ArrayField vs One-to-Many relationship
body: <p>For a model in my database I need to store around 300 values for a specific field. What would be the drawbacks, in terms of <strong>performance</strong> and <strong>simplicity in query</strong>, if I use Postgres-specific <a href="https://docs.djangoproject.com/en/dev/ref/contrib/postgres/fields/#arrayfield" rel="noreferrer">ArrayField</a> instead of a separate table with One-to-Many relationship?  </p>
