PostgreSQL connection pooler, load balancer and query router. Pools client connections, spreads read-only queries across streaming-replication standbys, and detaches a backend that fails its health check.

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
