It would be awesome if arel supported least and greatest.

Here's the documentation I've found for postgres and mysql.

I'd be up for trying to write a pull-request, any hints on where to start? I'm guessing that I'd need to make a new node in lib/arel/nodes as a subclass of Function or at the bottom of lib/arel/nodes/function with Sum, Max, Min, etc ...

ARel already has a NamedFunction node that can be used for any functions like this -- is it not working for you?

Sorry for the late reply. I guess I could just use the NamedFunction. It's more of a convenience thing than anything else.
