This is a really cool feature, but it's not what we need. The "canonical" refers to the URL, not the web page. It's
onlysupposed to be used if you have multiple URLs that are actually the *same* page; the "canonical" URL tells Google
"useonly this URL for this page."
But in our case, the Postgres manuals for each release have different URLs *and* different content, so the "canonical
URL"isn't the right solution.
