page.page_latest point to the current revision.rev_id However, you shouldn't be able to have several revisions with the same rev_id. Even if something went horribly wrong at the wiki level, rev_id is a PRIMARY KEY. How did you do the import? I suspect you may have broken something importing or merging. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
