TL;DR Built a simple web tool to help the PostgreSQL community quickly compare feature differences between any two database versions. Saves time when planning upgrades or evaluating version capabilities.
If you’ve ever tried planning a PostgreSQL upgrade, you know the drill: open the official Feature Matrix, scroll through hundreds of rows, and mentally track which features changed between version X and version Y. The matrix is comprehensive and authoritative, but it shows all versions at once—making it tedious to identify what specifically changed between two releases.
I built pgfeaturediff.com as a simple solution: select any two PostgreSQL versions and instantly see a differential view of what was added or deprecated between them. No more manual scanning through tables.
The tool runs a weekly automated scraper that parses the official PostgreSQL Feature Matrix, validates the data, and publishes it as clean JSON. The React frontend then provides filtering, search, and shareable URLs for specific comparisons. Everything is static, hosted on GitHub Pages, and costs nothing to run.
It’s a small tool, but it’s being used by DBAs and developers globally when they need to quickly understand version differences. Sometimes the simplest solutions—just presenting existing data in a more useful way—are exactly what a community needs.
