Description of Changes
This is the first of several patches that will close/implement #2442. This one in particular adds a utility for expanding or resolving RLS rules in a logical query expression, but it does not integrate it into compiler. That will happen in a follow on patch along with integration tests.
API and ABI breaking changes
None
Expected complexity level and risk
2.5
The logic is straightforward. There are a few parts that may be non-obvious like tree rotations and alpha conversion. I've tried to add ample documentation around those parts.
Testing
Integration tests will be added with in the integration patch.
