psycopg2.errors.InsufficientPrivilege: permission denied for relation django_migrations

问题

What my settings.py for DB looks like:

ALLOWED_HOSTS = ['*']

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'fishercoder',
        'USER': 'fishercoderuser',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

I have created a new and empty db named "fishercoder" this way:

psql -U postgres
create database fishercoder; 
ALTER USER postgres with password 'badpassword!'; 
CREATE USER fishercoderuser WITH PASSWORD 'password';
ALTER ROLE fishercoderuser SET client_encoding TO 'utf8';
ALTER ROLE fishercoderuser SET default_transaction_isolation TO 'read committed';
ALTER ROLE fishercoderuser SET timezone TO 'PST8PDT';
GRANT ALL PRIVILEGES ON DATABASE fishercoder TO fishercoderuser;

Then I've imported my other SQL dump into this new DB successfully by running:psql -U postgres fishercoder < fishercoder_dump.sql

Then I tried to run ./manage.py makemigrations on my Django project on this EC2 instance, but got this error:

Traceback (most recent call last):
  File "/home/ubuntu/myprojectdir/myprojectenv/lib/python3.6/site-packages/django/db/backends/utils.py", line 86, in _execute
    return self.cursor.execute(sql, params)
psycopg2.errors.InsufficientPrivilege: permission denied for relation django_migrations

I found these three related posts on SO: One, two and three

I tried the commands they suggested:

postgres=# GRANT ALL ON ALL TABLES IN SCHEMA public to fishercoderuser;
GRANT
postgres=# GRANT ALL ON ALL SEQUENCES IN SCHEMA public to fishercoderuser;
GRANT
postgres=# GRANT ALL ON ALL FUNCTIONS IN SCHEMA public to fishercoderuser;
GRANT

no luck, I then restarted my postgresql db: sudo service postgresql restart when I tried to run migrations again, still faced w/ the same error.

More debug info below:

Any ideas how to fix this?
