WorldQL uses Postgres under-the-hood to store permanent information. I was inspired by companies like TimescaleDB which build new functionality on top of Postgres’s rock-solid base.

Any high-availability solution for Postgres will also be available for WQL.

For the Minecraft world catch-up example, it’s as simple as querying Postgres for block records in a certain chunk after a certain timestamp. No fancy spatial stuff happens on the Postgres side.
