# PostgreSQL QoS Resource Governor We are pleased to announce the first beta release of Pg_QoS, a PostgreSQL extension that provides Quality of Service (QoS) style resource governance for sessions and queries.
## Project Overview Pg_QoS helps ensure more stable operation of the entire PostgreSQL instance/cluster by limiting resource usage, so that different workloads interfere with each other less. Enforce per-role and per-database limits via `ALTER ROLE`/`DATABASE SET qos.*` Per-database/role: - Limit CPU usage by binding the backend to N CPU cores (Linux only); planner integration ensures parallel workers stay within that cap - Track and cap concurrent transactions and statements (SELECT/UPDATE/DELETE/INSERT) - Limit for setting `work_mem` parameter ## Requirements - PostgreSQL 15 or newer (officially supported) - Build toolchain and server headers (`pg_config` must be available) - Linux for CPU limiting ## Repository https://github.com/appstonia/pg_qos ## Status This is an beta release intended for early testing and feedback. We welcome comments, suggestions, and contributions from the community. **Note:** As development is ongoing, please build and use the latest version from the main branch whenever possible. --- We'd love to hear your feedback via Github issues.
