* feat: Convert rego queries into SQL clauses

* Fix postgres quotes to single quotes

* Ensure all test cases can compile into SQL clauses

* Do not export extra types

* Add custom query with rbac filter

* First draft of a custom authorized db call

* Add comments + tests

* Support better regex style matching for variables

* Handle jsonb arrays

* Remove auth call on workspaces

* Fix PG endpoints test

* Match psql implementation

* Add some comments

* Remove unused argument
