I don't think you're over thinking it. I often have to look at such
settings and I'm probably not unique in when I glance at 30822MB I can
see that's roughly 30GB, whereas when I look at 31562138kB, I'm either
counting digits or reaching for a calculator. This is going to reduce
the time it takes for a human to process the pg_settings output, so I
think it's a good idea.
