Fake it till you make it - Extend functionality of your legacy application with fake tables

Concrete example: leihs legacy knows about roles for users. We would like to extend this to include roles for groups. But we can not change code of leihs legacy. Solution: we add new functionality but make leihs legacy belive the DB schema has not changed.

Principle Idea

1. Add new tables for new functionality, i.e. group_roles
2. Rename existing table, i.e. user_roles to direct_user_roles.
3. Create a view user_roles with custom AGGREGATEs using direct_user_roles and group_roles.
4. Optinally: make the views, i.e. `user_roles`` writable with triggers.
