The queue module has been dead since it was removed from core. Note that nobody bothered patching it for 4.7, and it does not have a .install file. The bigger question is: does any other module use this column in the database? Here is the answer from today's HEAD: $ grep "SELECT .*moderate" */*.module|awk -F: '{print $1}' | sort -u admnotify/admnotify.module category/category.module content_moderator/content_moderator.module ejournal/ejournal.module event/event.module eventfinder_filter/eventfinder_filter.module flexisearch/flexisearch.module hof/hof.module image_browse/image_browse.module linkattach/linkattach.module links/links_weblink.module nmoderation/nmoderation.module nodeperm_role/nodeperm_role.module pdfview/pdfview.module pr/pr.module queue/queue.module shazamgallery/shazamgallery.module shoutbox/shoutbox.module track/track.module tr/tr.module video/video.module weblink/weblink.module xstatistics/xstatistics.module Since this contains some obsolete modules, here is the same result from the 4.7 modules: $ grep "SELECT .*moderate" */*.module|awk -F: '{print $1}' | sort -u category/category.module content_moderator/content_moderator.module ejournal/ejournal.module event/event.module hof/hof.module nmoderation/nmoderation.module og_blocks/og_block.module pdfview/pdfview.module shazamgallery/shazamgallery.module shoutbox/shoutbox.module xstatistics/xstatistics.module More importantly, what will moderation modules do without that column, and how would they do it? Namely, the new content_moderator and nmoderation?
