I guess that we should do that at the end of the day.  A lookup at the
in-core tools I see three areas which stand out compared to the rest:
- pg_waldump, and attached is a patch for it.
- pgbench.  However for this one we also have some status messages
showing up in stderr output, and the TAP tests have dependencies with
the output generated.  This part is not plugged into the generic
logging facility yet, and we have 162 places where fprintf/stderr is
used, so that's kind of messy.
- pg_standby.  For this one, we may actually be closer to just remove
it from the tree :)
