I am trying to use an Django multiple database configuration with MYSQL as my default database and redshift as my analytics database. My configuration looks sometime like this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'xxxx',
'USER': 'xxxx',
'PASSWORD': 'xxxx',
'HOST': 'localhost',
},
'analytics': {
'NAME': 'analytics',
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'USER': 'XXXXXXXXX',
'PASSWORD': 'XXXXX',
'HOST': 'XXXXX.us-east-1.redshift.amazonaws.com',
'PORT': 5439,
}
}
When I try to migrate my analytics app, using the following command
python manage.py migrate analytics --database analytics
I am seeing the following error:

Any ideas on how to resolve this issue? I am using Django==1.7.9
and psycopg2==2.6.1
