How to get Data Guide from Postgres

Hello,

I love the Data Guide feature and how it displays what fields are being utilized in a dashboard and how. I want to pull this data from the Postgres database on Tableau Server to report on what fields are used where. However, I have had very little luck. I am using the Tableau Data Dictionary to assist me. So far, I have tried using the fields field from public.views but a majority of the data is not present. I have looked a couple other tables that contain field such as the datasources table but have had the same result.

My question is am I able to pull Data Guide from the Tableau Postgres Database or is it all created on the fly in the Tableau Server client?

Thanks,

Zack
