I'm developing it for a long time, do you register an email with the postgresql user?

I am currently using postgresql 9.4 with postgis 2.1.

I'm trying to make an application with a long storage. When I tried to install django-allauth, when python3 manage.py migrate

Due to a lengthy error, django.db.utils.ProgrammingError: relationship "account_emailaddress" does not exist

occurs.

When I looked it up, I thought it was an error related to DATABASE.

So I remembered that if there was an e-mail box when I installed Post-Grescuel and created a user, I would have omitted it. I wonder if there is a way to register an email with an already existing user or register an email together when creating a user.

I understand that you are using postgres, the default user. I'm a beginner, so I don't know.

I'd appreciate it if you let me know.
