Yeah, but it doesn't seem very likely, because:

1. If the system is on the Internet, it's definitely being attacked, and

2. The attacks that connect to a port and then disconnect are not the
ones you should be most worried about, and

3. The right way to detect attacks is through OS-level monitoring or
firewall-level monitoring, and nothing we do in PG is going to come
close to the same value.
