Precisely.    The big problem with memory caching is the cache getting out of
sync with the database.   Updating the cache through database triggers helps
ameliorate that.

However, our inability to pass messages with NOTIFY somewhat limits the the
utility of this solution   Sean wants "on commit triggers", but there's some
major issues to work out with that.   Passing messages with NOTIFY would be
easier and almost as good.
