This is very interesting code that uses Umbra v0.2-957, PostgreSQL 17.2, and DuckDB v1.1.3.
One minor point: some of the problems could not be implemented in DuckDB due to a missing xor operator - but the documentation includes an xor function (https://duckdb.org/docs/sql/functions/numeric.html#xorx-y) for the same version. Is the form of the function not suitable?
