I've got no doubt that there are *some* "non corner" cases for which this would be a win. The lower the update load on the database, the better it's going to look. The issue really is where does it start being a loss, and can you convince us that those cases are all "corner" ones? (The subtext here, of course, is the assumption that it's an all-or-nothing choice. I'm of the opinion that supporting both options would be infeasible from a code complexity and maintenance standpoint; but a simple patch that did both would of course prove that opinion wrong ...) regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
