Production Grade RAG pipeline That Admits "I Don't Know"

A production-grade RAG pipeline is being built using Postgres, pgvector, FastAPI, Gemini, Celery, and Redis. This pipeline is designed to provide answers that cite their sources, refuse to answer when information is unknown, and enforce row-level security directly within the database. The project aims to create a robust system capable of admitting "I Don't Know" when appropriate, ensuring reliable and secure information retrieval.
