PostgreSQL's LISTEN/NOTIFY system can be used to send signals from the
backend to any connections which are listening for it.  I wouldn't want
to require such capability, however, as not all databases will have it
and not all users will by savvy enough to understand how to use it.
Certainly would be nice as an option though, both for this and perhaps
for in-memory cacheing of often-requested results.
