Keep in mind that you've got to be really, really conservative about
adding functionality in the logging collector process.  If it ever
crashes, we have problems.  If memory serves, the postmaster is able
to restart it, but we cannot restore the original stdout/stderr
destination, which is problematic if that's where its output had
been going.  So it's pretty close to being as mission-critical as
the postmaster itself.
