FATAL: database does not exist

I have a difficult time settings django with postgres.

Here is my settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'HOST': 'localhost',
        'NAME': 'collector',
        'USER': 'collector_user',
        'PASSWORD': 'collector'
    }
}

I created the user collector_user with password collector as in Postgres First steps website. Also created the collector schema:

postgres=# select nspname from pg_catalog.pg_namespace;
      nspname       
--------------------
 pg_toast
 pg_temp_1
 pg_toast_temp_1
 pg_catalog
 public
 information_schema
 collector
(7 rows)

And here is what django has to say about that:

Traceback (most recent call last):

    conn = _connect(dsn, connection_factory=connection_factory, async=async)
django.db.utils.OperationalError: FATAL:  database "collector" does not exist

I also tried dropping the DB and the user and try creating it again. It also didn't work. What might be the problem? Is there something I didn't do? I'm new to postgres, I work on MySQL normally.

In PostgreSQL, a schema is not a database. You created a schema named 'collector' in the database named 'postgres'. But you trying to connect to database named 'collector'. Which does not exist, because you didn't create it. You should probably create a database named 'collector', and then just leave the schema alone (i.e. default to 'public').

Creating a new schema in the 'postgres' database is usually a bad practice anyway, as the database named 'postgres' should usually be reserved for system maintenance tasks.
