Just a thought, but couldn't psql be made to use the binary mode of
libpq and do at least some of the conversion on the client side? Or
does binary mode not work with copy (that wouldn't suprise me, but
perhaps copy could be made to support it)?
The other thought, of course, is that you could use PITR for your
backups instead of pgdump...
