Because it's not being issued in a user's session.  The only place it
can go is to the system log, and if you use a level of WARNING or less,
it's likely to get filtered out by log_min_messages.

I'm totally unimpressed by the argument that log-filtering applications
don't know enough to pay attention to LOG messages.  There are already a
lot of those that are quite important to notice.
