Alright gentlemen here we go, take two.
backup.sgml-cmd-v002.patch addresses your feedback and offers a better worded statements that avoid implying that some features are being deprecated when it isn't the case. We also spent some more time polishing other details, like making adjustments to the tone of the text so that it sounds like a manual, not a blog post, more importantly, making it clear that superuser privileges are not always required to perform a successful backup in practice as long as the role used to make the backup has sufficient read privileges on all of the objects a user is interested in. We also mention and show examples of usage for pigz alongside with gzip, and probably something else too :P Please, see the diff file attached to this message for complete and detailed log of the changes.
