This is most likely a bad idea for reasons that have nothing to do with
security. Consider what happens when the trigger executes and later in
the transaction there's an error, causing the whole transaction to roll
back. Now the outside world has changed state and your database has
not.
It's usually better to have an application process that is in charge of
monitoring database state and updating external stuff to match. See the
archives for many previous discussions of this point.
