Instead of opening and closing a new database connection for each request\u2014an expensive operation\u2014the pool maintains a set of open connections that applications can borrow and return, reducing latency and resource consumption in concurrent workloads.\n\nThe package exports a ThreadSafeConnectionPool class that manages a minimum and maximum number of connections, handing them out on demand and recycling them back into the pool. It is designed for multi-threaded Python applications that make frequent database queries and need to amortize connection setup costs. The library depends only on psycopg2-binary and installs as a pure Python wheel.","worth_installing":"Yes, if you are building a multi-threaded Python application that queries PostgreSQL frequently. The package is simple, has low install friction, carries no known vulnerabilities, and solves a real problem. The dormant maintenance status is a minor concern\u2014monitor for breaking changes in psycopg2 or PostgreSQL\u2014but the code is stable.
