Found when working on a production outage where the recreated row wasn't there, we noticed that the user_experience one wasn't present:
INSERT INTO /*_*/pagetriage_tags (ptrt_tag_name, ptrt_tag_desc) VALUES ('user_experience', 'Experience level: newcomer, learner, experienced or anonymous' );
Present on enwiki. (The DB for test2wiki is very out of date and probably should just be dropped with the extension.)
