Include this URL or one like it in any TODO about this:

http://publib.boulder.ibm.com/infocenter/rb63help/topic/com.ibm.redbrick.doc6.3/sqlrg/sqlrg36.htm#sii-06-62323

It would be wonderful having this stuff but I'll say just skimming it was
giving me headaches imagining how much work it would be to do right.

Just having a few windowing functions like rank() and functions like running
averages would go a long way to making people happy though.
