Psycopg C-optimized

Psycopg 3 is a modern PostgreSQL database adapter for Python, designed to leverage modern Python (asyncio, static typing) and PostgreSQL features (binary protocol, pipeline mode). `psycopg-c` is an optional component providing C-optimized speedups for the core `psycopg` library, offering performance benefits over the pure Python implementation. It is actively maintained with frequent updates, currently at version 3.3.3.
