This is because it didn't always exist. Legacy redirects (that have
not been changed in the last . . . maybe year?) will have
page.page_is_redirect set to indicate that they're a redirect. The
old way then just parsed the text of the page for a target.
It's possible to fix this using maintenance/refreshLinks.php, but
nobody's done it on Wikimedia wikis, apparently. It would be a pretty
big operation on the large ones, of course, but I don't think it
should be unmanageable at all, assuming the script is sane and only
tries parsing pages with page_is_redirect but no redirect table row.
You'd have to ask someone with shell access to do it.
