That's because you don't run libpq in any contexts where that behavior
is inappropriate ... but there are plenty such contexts. Most GUI
applications will want to trap any and all notices and put them up in
a window; sending to stderr is likely to mean sending to /dev/null,
or at best a logfile that the user will never look at.
