PGSimCity
Explore PostgreSQL internals as an interactive 3D city.
About PGSimCity
PGSimCity turns a PostgreSQL cluster into an explorable 3D city. Follow connections through backends, shared buffers, WAL, storage, checkpoints, vacuum, and replication; run guided scenarios or walk the city at eye level. It is an independent educational model—not a PostgreSQL emulator—and clearly documents its simplifications.
