In this section, we will take a closer look at two other PostgreSQL libraries for Python. The first one, pg8000, also implements the DB API 2.0. This makes it very similar to psycopg2. The difference though is that it is not dependent on the library ligpq and is written entirely in Python. This makes the library very lightweight and applications, that would use it, easily portable.

The second one, asyncpg, does not implement the Python DB API. It uses a binary protocol to communicate with a PostgreSQL database and asynchronous API in the applications. This makes it possible to create very fast database applications performing great amounts of commands in a short time.
