Any reason why there isn't a Postgres KV store implementation? This could then have postgres working as the document store, index store and vector store (with pgvector).
New to llama index and want my existing PGVector RAG to work with how they do things here.
hey @Wizboar, good question. RE KV store, we just haven't gotten around implementing it. This is an area we'd love a community contribution in!
That being said. You can already use PGVector RAG with just the postgres vector store integration (nodes are already store in the postgres by default). There are just a small subset of features require a separate document store.
