Can you demonstrate that this is actually a serious concern next to the
total time spent launching a backend? I can't measure any real change
in total time for "psql -l" when log_hostname is enabled, which should
be a comparable hit.
I started out proposing a one-line change. The odds of this ever
getting done drop by an order of magnitude every time someone proposes
another order-of-magnitude increase in the work required...
