Django 如何知道我的数据库的路径

只是在学习Django教程之后，我决定用Postgresql而不是SQLlite来完成这些教程.

我在设置文件中添加了以下内容，一切正常:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'django_tutorial',
        'USER': 'django_admin',
        'PASSWORD': 'password123',
        'HOST': '127.0.0.1',
        'PORT': '5432'
    }
}

django_tutorial=> \dt
                     List of relations
 Schema |            Name            | Type  |    Owner
--------+----------------------------+-------+--------------
 public | accounts                   | table | django_admin
 public | auth_group                 | table | django_admin
 public | auth_group_permissions     | table | django_admin
 public | auth_permission            | table | django_admin
 public | auth_user                  | table | django_admin
 public | auth_user_groups           | table | django_admin
 public | auth_user_user_permissions | table | django_admin
 public | django_admin_log           | table | django_admin
 public | django_content_type        | table | django_admin
 public | django_migrations          | table | django_admin
 public | django_session             | table | django_admin
(11 rows)

我的问题是-How does Django know where postgresql is located? Originally I thought the name was supposed to be the C:\ path, but it only needed the DB name?

例如，文档对sqllite的描述如下:

The name of the database to use. For SQLite, it’s the full path to the database file. When specifying the path, always use forward slashes, even on Windows (e.g. C:/homes/user/mysite/sqlite3.db).
