PGSimCity Turns PostgreSQL 18 Internals Into an Interactive 3D City
PGSimCity, a new open-source tool by Nikolay Samokhvalov, visualizes PostgreSQL 18 internals as an interactive 3D city in the browser. It maps database components to districts, allowing developers and SREs to simulate operational pathologies like checkpoint storms and table bloat. Built with real PostgreSQL code via PGlite, it offers a hands-on way to understand query execution and system behavior.
