Is your feature request related to a problem? Please describe.
Feature is related to correctness of the RW engine.
Describe the solution you'd like
- Our Regression tests uses differential tests against PG and RW
- Test cases currently are text-based. Missing an empty space results in test failures. We should port the format to something a bit smarter.
- Take existing test cases #5156 (from e.g. DuckDB) and port them automatically to suite RW. This would require some templating to add special keywords from RW to the test cases.
