pgvector
Open-source vector similarity search extension for PostgreSQL.
About
pgvector is an open-source extension that adds vector similarity search to PostgreSQL, letting you store embeddings alongside existing relational data and query them with exact or approximate nearest-neighbor search using IVFFlat or HNSW indexes. It supports L2, inner product, cosine, and L1 distance and keeps Postgres features like ACID compliance and JOINs. Released under the PostgreSQL license.
