How We Made PostgreSQL as Fast as Pinecone for Vector Data

Pgvectorscale, a new PostgreSQL extension, offers advanced indexing techniques for vector data. It improves approximate nearest neighbor (ANN) query performance by implementing the DiskANN algorithm, which allows SSD storage, and introducing SBQ (statistical binary quantization) for better accuracy. This advancement competes with specialized databases like Pinecone without sacrificing PostgreSQL's extensive feature set.
