Add the ability to access and use database meta data in the function stack.

Please, please add the ability to access and use database (tables, relationship, content, columns) meta data in the function stack instead of calling them from the api. We should be able to use them like every custom or inbuilt function. It would be great!👌. I imagine how quickly it can help my app to be able to easily query from all the tables referencing my users and/or employees tables and carry out some manipulations with/from them. The potential applications are enormous!
