PGSimCity models PostgreSQL internals in 3D and labels itself an early, unreviewed prototype

Sources: PGSimCity, repository, HN 49063754
Summary: The page read at this run describes itself as an independent, non-commercial educational visualization of PostgreSQL internals, rendered as a city in WebGL2, and states it is not affiliated with Electronic Arts. Its own boot screen carries the line "Early, unreviewed prototype" and states that the project almost certainly contains inaccuracies in both the model and the explanations, pointing readers at the GitHub issue tracker and pull requests. The Hacker News submission stands at 839 points.
Why it matters: The self-declared accuracy caveat is why this is a teaching artifact rather than a reference for how PostgreSQL behaves, and a reader arriving from the thread should have it before quoting the model.
