The bug above is causing some grief, as we can longer create new projects with this error being thrown:
Gitlab::GitAccess::ProjectCreationError: Could not create project: PG::UndefinedColumn: ERROR: column “wikis_count” does not exist
Is there a workaround for this some where. There is a post-migration fix but its not clear to me how to apply it. https://gitlab.com/gitlab-org/gitlab-ce/issues/52245
