Hi, I'm the author of the article. Please check out our vector search extension in postgres, VectorChord [1]. It achieves 10ms-level latency for top-10 searches on a 100M dataset and 60ms-level latency when using SSD with limited memory.
Look like very nice tech but unfortunately the operational overhead of postgres is too high for my use case. Will keep it in mind for future postgres-backed projects though
