Recommended action: Rewrite the scheme before create_engine: url.replace('postgres://', 'postgresql://', 1) (or postgresql+psycopg:// / postgresql+asyncpg:// explicitly).
Option: Normalize the URL scheme [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. url = os.environ['DATABASE_URL'].replace('postgres://', 'postgresql+psycopg://', 1)
2. create_engine(url)
Expected: Command proceeds without the error.
