No. All spatial queries use WorldQL’s in-memory k-d tree implementation and are not used for permanent world alterations.

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.

Could yo elaborate on why you don't use PostGIS? I've always assumed its C algorithms are high-performance.
