pgvector
Adds vector similarity search to Postgres, so embeddings live next to the rows they describe and you keep transactions, joins and backups you already understand. For most first RAG projects this is all the vector database you need, and the README is a clear explanation of HNSW, IVFFlat and hybrid search.
