Courageous to post this here, but I emphatically disagree. Any aggregation operation will effectively have undefined behavior. You could make it like a spreadsh

Courageous to post this here, but I emphatically disagree. Any aggregation operation will effectively have undefined behavior. You could make it like a spreadsheet where cells have both numeric data (either static or derived as in the case of a cell formula that sums things up, as an example) or functions, but if you want row/cell metadata per entry then that should be a new database type or some kind of extension. If I have a column that's defined (lol... hinted) as an INT then if I see a STRING or TEXT in one of the rows I'm gonna be pretty pissed. But it's ok, at least this is an exciting novelty to observe and shake one's head at.
