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.

Version

0.0.19 · latest0.0.180.0.17

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.

Verify the chart

cosign verify ghcr.io/quenchworks/charts/pgpool:0.0.19 \

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
