> That seems reasonable. Feel free to merge. You're basically working on the physical type and saving off the extension type to reattach later? Yeah exactly. > I think, longer term, we might want to consider doing this at the plan level. So nodes never have to know about the existence of extension types, and we simply attach them, as needed, in the sink. Might want to wait until we have a few compute functions for extension types first though so there is a bit more example. Huh, wouldn't there be cases where extensions would be relevant to the kernels? E.g. geographical coordinates in a certain projection (where extension would contain the projection) and [calculating haversine distances](https://en.wikipedia.org/wiki/Haversine_formula). -- This is an automated message from the Apache Git Service.
