This is a single static binary that connects to Postgres using a read-only role and prints a findings-first health report. It calculates cache hits, lock waits, and transaction age locally, writing a baseline file to track changes between runs. The tool runs entirely on your machine without requiring external agents, time-series databases, or write privileges.

It is useful for immediate insight into database performance without deploying new infrastructure. However, the human-readable output is explicitly unstable, so you must parse the versioned JSON contract for any automated scripts. If your workflow relies on the terminal text directly, you will face breaking changes.
