	tl;dr: PGSimCity is an educational, SimCity-styled interactive visualization that models PostgreSQL's internal engine to help users understand how it works. It's an early, unreviewed prototype that may contain inaccuracies, and contributions via issues or pull requests are welcomed. The project is independent and not affiliated with Electronic Arts.
	HN Discussion: ~Concept is appreciated but visualization is too busy and confusing to be effective ~Would benefit from being interactive, e.g. entering a query and walking through the flow ↑Excellent educational approach that could be applied to other complex technical domains ↓Skeptical of accuracy since it was vibe-coded quickly with AI assistance ↑AI-assisted learning tools like this are a great new way to explore complex topics
