Yeah, we could do that. But then again the question pops up what to do
about the other option that mentions defaults (-F) and the others which
have a default but it is not spelt out yet (-X, -Z at least) (output is
still from v15, additional options have been added since):
-F, --format=p|t output format (plain (default), tar)
-X, --wal-method=none|fetch|stream
include required WAL files with specified method
-Z, --compress=0-9 compress tar output with given compression level
So, my personal opinion is that we should really document -c because it
is quite user-noticable compared to the others.
So attached is a new version with just your proposed change for now.
