Whilst looking at something else I noticed the errors were being logged whilst music database is upgraded with an index already exists error.
Looking at the AddIndex method in DatabaseUtility.cs this attempts to return if the index already exists rather than trying to create it. Unfortunately the SQL and logic does not work (the second part of the UNION ALL is returning all temp table and their indexes)
