Hello, I'm trying to upgrade to 1.2.0 so i cloned our production database and am trying to run the ups-migrator but i'm getting a strange error about one of the new tables. I'm running a postgresql 9.6 database on centos 6.9 and wildfly 10.1 I'm attaching the full output of the migrator (.txt) as well as the contents of my changelog table (.xls) Any help getting unstuck would be greatly appreciated!
