Pg_QoS v1.0.0 stable release is out!
- Jump to comment-1AppstoniA via PostgreSQL Announce<announce-noreply@postgresql.org>Mar 3, 2026, 8:02 AM UTCWe are pleased to announce the first stable release of **Pg_QoS**, a PostgreSQL extension that provides Quality of Service (QoS) style resource governance for sessions and queries.
🔹 Project overview
Enforce per-role and per-database limits via ALTER ROLE/DATABASE SET qos.*
- 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 work_mem per session
- Fast, reliable cache invalidation across sessions (no reconnect) using a shared epoch mechanism
This makes it easier to ensure fair resource allocation
across different workloads running on the same PostgreSQL instance.
🔹 Requirements
- PostgreSQL 15 or newer (officially supported)
- Build toolchain and server headers (pg_config must be available)
- Linux for CPU limiting
🔹 Packages
Native packages are now available for the following distributions:
Packages can be found in the repository releases section and cover all PostgreSQL versions supported by Pg_QoS (15 and newer).- **Debian 13** (Trixie) - **Ubuntu 24.04** (Noble Numbat) - **Red Hat Enterprise Linux (RHEL) 10** - **AlmaLinux 10** - **CentOS Stream 10**
