## pg_datasentinel - Observability extension for PostgreSQL

We are pleased to announce the first release of pg_datasentinel.

- Source: [https://github.com/datasentinel/pg_datasentinel](https://github.com/datasentinel/pg_datasentinel)

## Features

- **Extended activity monitoring** — enriches pg_stat_activity 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.
