## What it is
A Ruby gem providing PostgreSQL performance diagnostics for Rails applications, ported from Heroku PG Extras. It exposes rake tasks, a Ruby API, and an optional web UI for queries about locks, index usage, buffer cache hit ratios, vacuum stats, and slow queries.

## Use cases
- diagnose slow postgres queries in a rails app
- check index usage and missing indexes in postgresql
- inspect database locks and blocking queries
- monitor buffer cache hit ratio and vacuum stats
- find most expensive sql queries with pg_stat_statements
- integrate postgres health checks into monitoring tasks

## When to choose
- you run a Ruby on Rails app on PostgreSQL and need performance insights without Heroku's plugin
- you want a scriptable Ruby API plus optional web UI for database diagnostics
- you need quick rake-task-based access to pg_stat_statements, locks, and cache stats

## When to avoid
- your app is not on Rails or Ruby (use ruby-pg-extras or the Node/Rust/Elixir/Python ports instead)
- you need full continuous database observability rather than on-demand diagnostics
- you use a database other than PostgreSQL

## Facets
- artifact type: library
- maturity: active
- function: database, monitoring, developer-tools
- domain: databases, developer-tools, performance, web-development
