Comment (by Simon Charette):
Did you make sure to add `django.contrib.postgres` to your
`INSTALLED_APPS`
[https://docs.djangoproject.com/en/3.0/ref/contrib/postgres/fields/#hstorefield
as documented]?
The latter is in charge of

registers] the necessary `psycopg2` adapters on connection creation.
If that's the origin of your issue I suggest we re-purpose this ticket to
add system checks to all `django.contrib.postgres.fields` that errors when
a field is used but `self.model._meta.apps.get('postgres')` is missing.
