+* (T172514) The following tables have had their UNIQUE indexes turned into proper
+ PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
+ langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
+ templatelinks, text, transcache, user_former_groups, user_properties.
+* IDatabase::nextSequenceValue() is no longer needed by any database backends
