No, because what normally goes to stdout is the dump data proper.
Commentary has to be sent to stderr to keep it separate.
As a general rule I don't think programs should have to read other
programs' stderr output at all --- certainly not for "did it work or
not" questions. What you ought to be doing is looking at pg_dump's
process exit code to find out whether it had a problem or not.
As for whether it's worth logging the stderr output for human
inspection: probably, but don't use -v. -v is *intended* to
create a lot of normally-useless chatter.
