Provides a connection pool for Psycopg 3, enabling efficient reuse of PostgreSQL database connections in Python applications.

Actively maintained with recent commits and low install friction. Single lightweight runtime dependency on typing-extensions. Distributed as a pure Python wheel.

Licensed under LGPL-3.0-only (copyleft). Derivative works and modifications must be distributed under the same license; proprietary applications using this package must comply with copyleft obligations or seek alternative licensing.

Usage

pip install psycopg-pool

from psycopg_pool import ConnectionPool

pool = ConnectionPool("postgresql://user:password@localhost/dbname")

Requires Python 3.10 or later; requires a running PostgreSQL server.

Verdict: Production-ready connection pool for Psycopg 3 with active maintenance, no known vulnerabilities, and straightforward installation. Copyleft licensing requires careful review if integrating into proprietary software. Well-suited for applications needing efficient PostgreSQL connection management.
