This should be simple, but for some reason I'm not quite sure what the solution is. I want to be able to update the value of a column for rows that have been updated. More specifically, if a row is updated, I want it's modified_date column to be populated with the current time stamp. I've looked at triggers and rules, and it looks like I'd need to create a function just to achieve this which seems incredibly clumsy and unnecessary. Could someone enlighten me?
