If you use the API to query the revision history of a Flow board, you get contentmodel: "flow-board" and *: "[]" for earlier non-Flow revisions of the content. This happens even where $wgContentHandlerUseDB = true; Sample: https://www.mediawiki.org/wiki/Special:ApiSandbox#action=query&prop=revisions&format=json&rvprop=timestamp|user|contentmodel|comment|parsedcomment|content&rvlimit=20&titles=Talk%3AFlow Maybe this will fix itself when we remove Flow's Occupation controller. Workaround: use Special:Export and uncheck "Include only the current revision, not the full history."
