Dump existing data:

docker-compose run --no-deps --rm web python manage.py dumpdata > datadump.json

Change settings.py to Postgres backend. Make sure you can connect on PostgreSQL. Then:

docker-compose run --no-deps --rm web python manage.py migrate --run-syncdb

Run this on Django shell to exclude contentype data

docker-compose run --no-deps --rm web python manage.py shell

>>> from django.contrib.contenttypes.models import ContentType
>>> ContentType.objects.all().delete()
>>> quit()

Finally:

docker-compose run --no-deps --rm web python manage.py loaddata datadump.json
