What pgvector does

Vector databases store embeddings and support similarity search. The important differences are index type, filtering, hybrid search, latency and operational overhead.

Most RAG failures come from retrieval quality, not from the database. Test hybrid search and metadata filtering on your own documents before choosing a vendor.
