Sure, and I was really tempted to do that until I noticed that we pass
down progname for fallback_application_name in the connection string
and that we would basically need to externalize progname in logging.h,
as well as switch all the callers of pg_logging_init to now include
their own definition of progname, which was much more invasive than
the initial refactoring intended.  I am also under the impression that
we had better keep get_progname() and pg_logging_init() as rather
independent things.

Missed those in the initial cleanup.  Applied, thanks!
