I think there's some sort of "to do" on that...

It ought to be not *too* difficult (I imagine!) to be able to
associate a trigger with the TRUNCATE action, and therefore run some
stored function any time TRUNCATE takes place.

For the Slony-I replication system, it would be attractive for this to
lead to attaching two functions:
  - One function would return an exception so that TRUNCATE against
    a subscriber node would fail...

  - Another would pretty much be as simple as submitting an event;
    perform createEvent('_ourcluster', 'TRUNCATE_TABLE', table_id);

A new event, TRUNCATE_TABLE, would do a TRUNCATE against the
subscribers.

This represents a pretty easy enhancement, given the new kind of
trigger.
