"Skipping upgrading messages table since it was already upgraded by another Q2A site sharing it. " => Is that part of the log?? What does it mean?

Answer 1

This is my imagination, and there are no grounds in particular. But, because there are no problem in my upgrade test, I think it is caused by some addon(e.g. theme, plugin) or interruption of upgrading. I think addon is the most doubtful.

Is there addon (theme, plugin, etc) that adds "name" field to "qa_posts" table?

If my reasoning is right, coping may be difficult a litle. This is because the same name field may be used for the different purpose.
