We don't support triggers of any kind on views.
One possibility for an alternative mechanism is to allow triggers on
views --- but I'm not sure exactly how this would work, or if it would
solve all the problems. At the very least it would answer the "data
stability" issue, since I suppose the trigger would receive precomputed
rows that wouldn't change while it executed.
