获取错误:将备份恢复到5.x Greenplum DB时，无法识别配置参数"gp_strict_xml_parse“

Question

我目前使用的是4.3.0的GreenPlum版本，现在我想转到5.8.0 GreenPlum版本，这是最新的版本。由于我的旧设置包含大量数据，因此我希望备份和恢复这些数据。

为了备份，我在我的4.3.0 Greenplum机器上运行了以下命令：

gp_dump --gp-d <Backup Location> <DB_Name>

此命令成功执行，并且我获得了命令中指定的DB的备份。现在，当我运行该命令时，即

gp_restore --gp-d <Backup Location> --gp-k <Timestmap Key generated while creating backup> -d <DB_Name>

要在我的5.8.0 Greenplum上恢复备份，我收到以下错误：

经过深入研究，我发现在GreenPlum 5.x版本中不再使用"gp_strict_xml_parse“变量。有没有办法解决这个问题，或者有什么办法在备份数据时不包括这个变量？

Answer 1

Greenplum版本5.x.x.x没有gp_strict_xml_parse参数。

在……里面

在5.x和更高版本中恢复(从4.3.x和更高版本创建的备份)时，您可以在恢复时忽略此错误/警告。因为这些警告不会影响恢复过程。

(注:我试过了，PIVOTAL的文档中也提到了同样的内容)
