It's denormalized data, so I'd assume that those are just errors of some kind. If you need to be really really sure whether something is a redirect, you have to parse its text (it's just a regex, should be somewhere in includes/Article.php or something). That's the authoritative check, which IIRC is used when actually deciding whether to redirect. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
