Those predate v18, so while might be able to mark them deprecated, I doubt
we'd remove them anytime soon.  

FWIW I don't have a tremendously strong opinion about --statistics-only.
I'd probably vote to remove it because 1) it's redundant, 2) once you add
an option, it's hard to remove it, and 3) pg_dump already has so many
options.  But I won't cry too hard if we keep it around.
