If a view lacks an INSTEAD OF trigger, DML on it can only work by rewriting the command into a command on the underlying base table(s). Then we will fire triggers attached to those table(s), not those for the view. This seems appropriate from a consistency standpoint, but nowhere was the behavior explicitly documented, so let's do that. There was some discussion of throwing an error or warning if a statement trigger is created on a view without creating a row INSTEAD OF trigger. But a simple implementation of that would result in dump/restore ordering hazards. Given that it's been like this all along, and we hadn't heard a complaint till now, a documentation improvement seems sufficient. Per bug #15106 from Pu Qun. Back-patch to all supported branches.
