## Which issue does this PR close? None AFAIK. ## Rationale for this change We regularly want to allow queries of the form ```sql SELECT * FROM records WHERE end_timestamp - start_timestamp > interval '2 seconds' ``` Until now that failed with ``` type_coercion: Cannot infer common argument type for comparison operation Duration(Microsecond) > Interval(MonthDayNano) ``` While working on that, I discovered you couldn't compare to an interval with the interval as the left hand side of the operation, so I fixed that too. ## What changes are included in this PR? * fix `Duration` vs. `Interval` comparison - sense check - is it really as simple as it looks? * support more operators in machinery to support intervals as the LHF of binary operations * add tests for both ## Are these changes tested? Yes ## Are there any user-facing changes? Should be only the above changes to support SQL. -- This is an automated message from the Apache Git Service.
