This is a metapackage bringing in postgresql_asyncpg extras requires for python3-sqlalchemy. The choice between This is a metapackage bringing in postgresql_asyncpg extras requires for python3-sqlalchemy. sqlalchemy. Note AsyncSession uses SQLAlchemy’s future mode, which has several potentially breaking changes. The entire stack is connected using the asyncpg Database Client Library, which provides a robust and efficient way to interact with PostgreSQL databases in In this article, we’ll walk through a standard async PostgreSQL setup using SQLAlchemy, explain why each piece exists, and show how I’m building a small project using FastAPI + PostgreSQL and I want to use async SQLAlchemy sessions for queries.
