Why the models rank pgvector — on best vector database for production rag
“For teams already on Postgres, the strongest real-world value — vectors live next to relational data, so joins, transactions, and exact metadata filtering are free; pgvectorscale's StreamingDiskANN and quantization closed most of the performance gap; zero new infrastructure to operate, works on RDS/Supabase/Neon. Near-tie with Qdrant — rank flips if you already run Postgres.”
