I have been calculating the maximum humidex for a given month (or for 'all time'), assuming that in any given period, the day with the maximum heat index will also be the day with the maximum humidex. While heat index and humidex are measurements of how hot it feels outside, they are calculated using different factors.

I now suspect the day with the highest heat index may not have the highest humidex. Is there a way to find the maximum humidex in a month, year, etc., given that it's a derived parameter and not stored in the database?

humidex is in the wview_extended schema. But, if you're using the legacy wview schema, then you would have to write an xtypes extension that knows how to calculate aggregates for humidex.

But, this makes me think that the xtypes system should really know how to calculate aggregates for any derived type. I've created issue #864 to track.
