We are pleased to announce the first release of pg_datasentinel.
- Source: https://github.com/datasentinel/pg_datasentinel
## Features
- Extended activity monitoring — enriches pgstatactivity with per-backend memory usage, live temporary file bytes, and (PostgreSQL 18+) the current execution plan ID per backend.
- Container resource visibility — reports CPU quota, memory limits, current memory usage, and CPU pressure for PostgreSQL running inside Docker, Kubernetes, OpenShift, or any cgroup-managed environment.
- Wraparound risk estimation — tracks XID and MXID consumption rates and provides live ETAs to the aggressive-vacuum and wraparound limits.
- Log capture into queryable views — records vacuum, analyze, temporary file, and checkpoint events into shared-memory ring buffers with parsed counters and timings available for real-time querying.
## Requirements
- PostgreSQL 15 or newer.
