Python psycopg2.errors.InsufficientPrivilege:拒绝关系django_迁移的权限

my settings.py for DB的外观：

ALLOWED_HOSTS = ['*']

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

我通过以下方式创建了一个名为“fishercoder”的新的空数据库：

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;

然后，通过运行：

psql-U postgres-fishercoder

然后，我尝试在这个EC2实例上的Django项目上运行

/manage.py makemigrations

，但出现以下错误：

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

我在上面找到了这三个相关的帖子： ，及

我尝试了他们建议的命令：

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

运气不好，然后我重新启动了我的postgresql数据库：

sudo服务postgresql重新启动

当我再次尝试运行迁移时，仍然面临相同的错误

更多调试信息如下：

有什么办法解决这个问题吗？

请尝试使用下面的命令，这对我很有效

GRANT rds_superuser TO username;

你确定你知道django_migrations在哪里以及谁拥有它吗？在psql中\dt django_迁移显示了什么？还有\dp django_迁移？谢谢@AdrianKlaver，我刚才运行了这两个命令并在问题中添加了输出。有趣的是，我还有一个EC2实例，我的另一个Django项目运行得非常好，这两个命令显示的结果完全相同\dt*.django_migrations刚刚添加了这个命令的输出@阿德里安：你能修好吗？我在尝试导入db以使项目在本地运行时遇到相同的问题。还可以在导入数据库转储后立即获取
