pg_dump why no indicator of completion

I've been working with pg_dump and one thing that's always struck me as strange is that there never seems to be an indication in the log that the pg_dump process completed successfully.

For example, I've been running a bunch of backups with pg_dump in directory mode with multiple jobs.  When I come back several hours later there are no pg_dump processes running.  The log is filled with:

Other than trying to restore the multi terabyte database somewhere else is there any way to know that it actually finished successfully?

Why doesn't pg_dump add a line in the output like:

when it's completed successfully? 

This seems like a terrible oversight.

Am I missing something obvious?

Thanks,
