The update script flow.sql has INSERT INTO flow_definition ( definition_id, definition_wiki, definition_name, definition_type, definition_options ) VALUES ( unhex('4ffebfa36a3155f2416080027a082220'), 'wiki', ... The hardcoded 'wiki' should be wfWikiID(). I think doing the insert in a script run by $updater->addPostDatabaseUpdateMaintenance( '' ) might work; AFTv5 did this. Extension:Flow#Installing documents the issue.
Gerrit change #81253 fixed this!
