Timescale has open-sourced pg_vectorsearch, an index implementation for PostgreSQL that claims better performance than pgvector's built-in IVFFlat and HNSW indexes. The project offers an alternative for vector similarity search workloads in Postgres, targeting users who need faster approximate nearest-neighbor queries.
Background
pgvector is the popular PostgreSQL extension for vector similarity search, widely used in AI and LLM applications. As vector workloads grow, new indexing approaches compete to deliver better query performance.
