**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** If the `min`/`max` value of any join equijoin columns are not overlapping, and if the propagated statistics are exact, we can infer that the join will not produce any results back. Requires #3787 **Describe the solution you'd like** Propagate the information about the correctness of the input statistics, so we can use it in the `compute_inner_join_cardinality` to decide whether to give up or say the selectivity is 0. **Describe alternatives you've considered** Not doing this. Currently we just give up and not provide any cost estimates. **Additional context** None, originally from #3787. -- This is an automated message from the Apache Git Service.
