Pgcat is a PostgreSQL middleware solution providing connection pooling, sharding, load balancing, and failover management. It functions as a proxy that optimizes resource usage and scalability by managing database sessions and distributing queries across multiple instances. The system distinguishes itself through traffic mirroring, which duplicates live production queries to test databases for validation. It also implements a sharding proxy to distribute data and queries across multiple database instances based on sharding keys. The project covers high availability through automated failover
