No, what I was worried about is shell script(s) that invoke pg_upgrade
and have to pass down some of these options through multiple levels of
option parsing.

BTW, it doesn't seem like the "pg-" prefix has any value-add here,
so maybe "--dump-option" and "--restore-option" would be suitable
spellings.
