Comment (by Simon Charette):
FWIW [https://forum.djangoproject.com/t/django-4-2-is-a-2nd-autofield-
like-field-on-a-model-possible/28278/4 someone was able to implement] an
`IdentityField` which is kind of the equivalent of `GeneratedField` if it
supported `AS IDENTITY`. It's not the equivalent of `SerialField` though
but it demonstrates that all the pieces are there to implement it based on
`db_returning` and `pre_save` returning a `Default` expression.
