So, I just discovered the rules system. As I understand it, it can be used to rewrite queries before they are passed to the query processor. I was wondering if I could use this to resolve a long standing frustration of mine. I often need to declare a column as NON NULL, and create a trigger/function to auto populate it with something more complex than a simple sequence. This need arises fairly often for me, and I would like to come up with a good way to implement this.
