Different set of indexes. Pgvectorscale adds disk-friendly indexes and works on top of vanilla postgres + pgvector, while pgvecto-rs seems to rewrite the existing pgvector indexes in rust with a few implementation optimizations. It also seems to handle its storage separately from the postgres storage engine
