Comment 8 for bug 733658

This also affects being able to use arbitrary SSH keys for remote backups. We have a specific key used to login to the backup server from the database server. The backup process runs as root, so while we are able to specify a key using the scpopts, the ssh part of the backup fails unless root's private key is the backup key, which we don't want to do, or share the same ssh config, which we again don't really want to do. Having a --sshopt option seems much better for us, as we cannot do remote backups without hacking up the script until this is completed.
