namespaceDupes.php is used when introducing a new namespace, to check/move titles that already use the new (namespace) prefix to be introduced. The actual rename happens in NamespaceConflictChecker::resolveConflictOn() in namespaceDupes.php. All it does is update the pages in the `page` table. However, there are plenty of other places that reference such namespace/title pairs that are not properly updated. Is there any reason NamespaceConflictChecker::resolveConflictOn() doesn't use Title::moveTo? That one does seem to update references in a lot of the other tables as well, and runs hooks (TitleMove & TitleMoveComplete) that extensions can subscribe to in order to update their data. Can we change it to use Title::moveTo? -- A non-exhaustive list of tables with namespace/title references that may contain incorrect references after such rename: * abuse_filter_log * archive * cu_changes * echo_event * edit_page_tracking * flaggedrevs_tracking * flaggedtemplates * flow_ext_ref * flow_wiki_ref * flow_workflow * globalimagelinks * hidden * imagelinks? * job * lgging * pagelinks * protected_titles * querycache * querycachetwo * recentchanges * redirect * templatelinks * thread * translate_stash * watchlist -- When Flow recently introduced Topic:, we encountered a problem with unmoved references in `watchlist` table: https://bugzilla.wikimedia.org/show_bug.cgi?id=71109
