AI Smart Assistant - Retrieval Augmented Generation

**Is your feature request related to a problem? Please describe.**
Currently, which part of the database objects needs to be sent as part of the AI prompt is to be selected manually by the user.

**Describe the solution you'd like**
Store the database metadata in a vector database and query it to find tables relevant to the user's request automatically. Then add only the relevant objects to the prompt instead of all of them (or requiring the user to explicitly decide which are relevant)

**Describe alternatives you've considered**
n/a
