🔌 Relational & Multi-Model Extensions (SQL + Vectors)
- pgvector (
pgvector/pgvector): An incredibly popular, open-source vector similarity search extension for PostgreSQL. It allows you to store, index (using HNSW or IVFFlat), and query embeddings directly alongside your standard relational data using pure SQL.
👉 pgvector/pgvector GitHub Repository [1, 2, 3, 4, 5] - LanceDB (
lancedb/lancedb): An open-source, serverless vector database built on top of the Lance columnar data format. Written in Rust, it can run embedded directly inside your application (like SQLite) and allows you to query vectors and disk-backed data with zero infra overhead.
