Rather than implementing the critical state resolution algorithm that's the core of Matrix, they just directly insert the latest state into the database. That'll instantly lead to diverging views of the room and incompatibility with every other implementation - and it's also a massive security hole.

$// Update room state if this is a state event if (event.state_key !== undefined) { await db.prepare( `INSERT OR REPLACE INTO room_state (room_id, event_type, state_key, event_id) VALUES (?, ?, ?, ?)` ).bind(event.room_id, event.type, event.state_key, event.event_id).run(); }$

Oh and to top things off, they make trivially false claims in their post. Tuwunel and its predecessors do not and have never used Postgres or Redis.

From Tuwunel to Workers
Our starting point was Tuwunel, a Rust-based Matrix homeserver designed for
traditional deployments. PostgreSQL for persistence, Redis for caching, filesystem for
media. Porting it to Workers meant questioning every storage assumption we'd taken
for granted.
