python3-psycopg3 3.1.3-0.1 (amd64 binary) in ubuntu lunar

 Psycopg 3 is a newly designed PostgreSQL database adapter for the Python
 programming language.
 .
 Psycopg 3 is a complete rewrite of Psycopg 2, maintaining the same
 fundamental libpq wrapper architecture and DB-API interface design, but
 exposing new features to better work with the newer versions of Python
 and PostgreSQL.
 .
 On the Python side, Psycopg 3 allows the use of asyncio-based
 concurrency and static typing. Many improvement to the Python interface
 make the library much simpler and more idiomatic to use,
 .
 On the PostgreSQL side, Psycopg 3 makes use of server-side parameters,
 prepared statements, binary parameters, and great support for COPY
 operations.
 .
 Psycopg 3 presents a familiar interface for everyone who has used
 Psycopg 2 or any other `DB-API 2.0` database adapter, but allows one
 to use more modern PostgreSQL and Python features, such as:
  - Strict Strong Typing
  - asynchronous support
  - server-side parameters binding
  - binary communication
  - a great integration of the COPY support
  - direct access to the libpq functionalities
