PostgresBench: A Reproducible Benchmark for Postgres Services

This is a great initiative. Benchmarking managed services is notoriously tricky due to varying configurations and 'black-box' optimizations. For anyone looking to run these benchmarks on their own or wanting to dive deeper into the why behind the numbers, pgmetrics (https://pgmetrics.io) is a fantastic open-source tool. It collects a massive amount of internal PG stats into a structured JSON format, making it easy to see exactly what's happening during a load test. For a more persistent and visual way to track these metrics across different providers, pgDash (https://pgdash.io) is built on top of that same data.
