Sonarqube从6.7.7 LTS迁移到7.9=>；错误：关系“；现场测量”；已存在（PostgreSQL）

数据库（PostgreSQL）迁移失败，原因是“创建表live\u度量值”失败

ERROR: relation "live_measures" already exists

将SonarQube从6.7.7 LTS更新为7.9 LTS时

非常感谢@jeroen heier 这为我指明了正确的方向。之后

DROP TABLE "live_measures";
ALTER TABLE organization_alm_bindings DROP COLUMN members_sync_enabled;
ALTER TABLE webhooks DROP COLUMN secret;

迁移成功完成。谢谢。

官方答案是恢复数据库并重试。但首先尝试删除手动提到的表，然后再次尝试开始迁移。如果成功，请检查最终结果，并将保存的数据库保留一段时间。
