You have a bunch of search indices on the post_subject column which has resulted in duplicate keys with a numbered suffix, but the original was deleted. When it looks at the search index, it can't find it for the post_subject field. I'm not sure how this happened, it looks like the Create Index button might have gotten pressed a bunch, but the UI doesn't allow that once an index is made.
Run these queries, then delete and re-create the index on the Maintenance tab.
