**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `ApproxMedian` is not fully implemented and calls `unimplemented!()` at runtime, so we can't call it from Python. It works in DataFusion because the SQL query planner translates the `approx_median` call to `approx_percentile`. It seems it is not possible to call `approx_median` from the DataFrame API currently. **Describe the solution you'd like** Have `ApproxMedian` delegate to `ApproxPercentile` instead of translating during planning. **Describe alternatives you've considered** None **Additional context** None -- This is an automated message from the Apache Git Service.
