New description:
BigAutoField is the default type of primary key now, and in Postgres,
regular IntegerField only goes up to around 2 billion. However, a couple
of pages still talk about the default primary key being an IntegerField.
Under https://docs.djangoproject.com/en/5.1/topics/db/models/#field-
options:
If you don’t specify primary_key=True for any fields in your model, Django
will automatically add an IntegerField to hold the primary key, so you
don’t need to set primary_key=True on any of your fields unless you want
to override the default primary-key behavior. For more, see Automatic
primary key fields
Under https://docs.djangoproject.com/en/5.1/ref/contrib/contenttypes
/#generic-relations:
2. Give your model a field that can store primary key values from the
models you’ll be relating to. For most models, this means a
PositiveIntegerField. The usual name for this field is “object_id”.
