A column page.page_no_title_convert is visible on ToolLabs (at least on dewiki_p). I have not found any extension using this field.
There is a entry in the HISTORY, a proposed schema change which seems not fully implemented:
https://www.mediawiki.org/wiki/Proposed_Database_Schema_Changes#New_field_in_table_page_for_languages_with_language_variants
Should be dropped, because it is unused. If this is not visible on production please move the task to ToolLabs. Thanks.
