what i'm looking for is a neat python library (or equivalent) that integrates end to end say with postgres/pgvector using sqlalchemy, enables parallel processing of large number of documents, create interfaces for embeddings using openai/ollama etc. It looks like FastRAG [0] from intel looks close to what i'm envisioning but it doesnt appear to have integration to postgres ecosystem yet i guess.
