Not define the name of the application via DSN "application_name=my_app_name"

[evgmoskalenko]

Hello, Could you tell me please, why I can't add application_name via DSN?

My DSN looks like:

from databases import Database

dsn = (
  f'postgresql://{user_name}:{password}'
  f'@{host}:{port}/{my_db_name}'
  f'?application_name=my_app_name'
)

db = Database(dsn)

Version:

• databases = "^0.3.1"

Hi! Easy-peasy. https://github.com/encode/databases/blob/master/databases/backends/postgres.py#L43

The workaround is to Database(dsn, **kwargs) and dsn.rsplit("&?").
