After furthing testing, I removed django_postgrespool (DATABASES['default']['ENGINE'] = 'django_postgrespool') and the error was finally more explicit about an integrity error. I was able to fix it and the error was gone.
Why the error is not the actual error when using django_postgrespool? Thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.
