pg_basebackup: incompatible server version 12.18
pg_basebackup: removing data directory "C:\Program Files\EMC NetWorker\Management\nmcdb_stage\pgdata"
Cause
在 NetWorker 19.11 中，Postgres 已更新到版本 12.18。但是， postgres_link Camera Control 下的 C:\Program Files\EMC NetWorker\Management\GST 仍然链接到 Postgres 11.21。
这是错误链接的示例：
<SYMLINKD> postgres_latest [C:\Program Files\EMC NetWorker\Management\GST\postgres\11.21]Resolution
请按照以下步骤解决此问题：
1） 转至 C：\Program Files\EMC NetWorker\Management\GST。
2） 删除链接postgres_latest。
3） 重新创建指向 Postgres 12.18 文件夹的链接。
mklink /D "C:\Program Files\EMC NetWorker\Management\GST\postgres_latest" "C:\Program Files\EMC NetWorker\Management\GST\postgres\12.18"
