Amazon redshift 在红移中创建表失败

我转储了一个红移表，正在尝试还原它。但是，还原时出现错误。我甚至尝试手动运行CREATETABLE命令，但它产生了一个错误。我想不出是怎么回事。谢谢

这是我收到的错误

ERROR:  syntax error at or near "tag"
LINE 38:     tag character varying(50),

tag

是Amazon中的一个保留字，根据它们的名称进行红移

您可以通过双引号强制执行：

...
"tag" character varying(50),
...

但是，您必须始终双引号引用该列名。更干净的解决方案是避免保留字作为标识符

---

不确定如何使用不带引号的

标记

作为列名生成该转储。可能使用的

pg_dump

版本与数据库版本不匹配？
