django 1.9: ProgrammingError: relation "users_user" does not exist

I am running into a ProgrammingError when doing migrate, I think it may be related to the use of django-allauth with a custom user. Here is what I do

1/ Create a fresh database with psql:

create database dj_example;

2/ Installed_apps contain django.contrib.sites:

DJANGO_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.admin',
)
THIRD_PARTY_APPS = (
'crispy_forms',  # Form layouts
'allauth',  # registration
'allauth.account',  # registration
#'allauth.socialaccount',  # registration
#'allauth.socialaccount.providers.twitter',
'djcelery', #Celery
)
LOCAL_APPS = (
'tucat.users',  # custom users app
}

3/ site_id is set to 1

SITE_ID = 1

4/ Custom user model is overly simple:

# -*- coding: utf-8 -*-
from __future__ import unicode_literals, absolute_import
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
  def __unicode__(self):
    return self.username

5/ Makemigrations works fine

# python manage.py makemigrations
Migrations for 'djcelery':
  0028_auto_20160601_1919.py:
  - Alter field status on taskmeta

6/ Migrate returns ProgrammingError: relation "users_user" does not exist

# python manage.py migrate
  Operations to perform:
  Apply all migrations: auth, contenttypes, djcelery, account, admin, sessions
  Running migrations:
  Rendering model states... DONE
  Applying account.0001_initial...Traceback (most recent call last):

psycopg2.ProgrammingError: relation "users_user" does not exist

The above exception was the direct cause of the following exception:

django.db.utils.ProgrammingError: relation "users_user" does not exist

Any idea of how to resolve that problem?

You have to delete the migrations folder and then, you should do

python manage.py migrate --run-syncdb

python manage.py migrate --fake appname
