An end-to-end open-source RAG stack on Postgres: pgvector for storage, pgai for embedding and generation inside SQL, Ollama for serving Gemma 2 and Llama 3.1 locally, and a 5-dimensional drift detector wired over the whole thing. Code, schema, and reproducibility receipts included.
Fully open-source RAG with pgvector + pgai + Ollama, and ragvitals watching for drift
