Still, apart from lack of interest from developpers and/or resources, is
there some reason we don't have a pg_dump --binary option?

DBA would have to make sure his exports are usable, but when the routine
pg_dump backup is mainly there to be able to restore on the same machine
in case of unwanted event (DELETE bug, malicious TRUNCATE, you name it),
having a faster dump/restore even if local only would be of interest.
