获取错误：无法识别的配置参数＆＃34; gp_strict_xml_parse＆＃34;同时将备份恢复到5.x Greenplum DB

Question

我目前正在使用4.3.0 GreenPlum版本，现在我想转移到5.8.0 GreenPlum版本，这是最新版本。因为，我的旧设置包含大量数据，我想备份和恢复数据。

对于备份，我在4.3.0 Greenplum机器上运行了以下命令：

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

此命令执行成功，我获得了命令中指定的DB的备份。 现在，当我运行命令时，即

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

要恢复我的5.8.0 Greenplum上的备份，我收到以下错误：

经过一番挖掘，我发现了＆＃34; gp_strict_xml_parse＆＃34; GreenPlum 5.x版本中不再使用变量。有没有办法解决这个问题，或者在备份数据时不以任何方式包含这个变量？

Answer 1

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

在

在5.x及更高版本中还原（从4.3.x及更高版本创建的备份） 您可以在还原时忽略此错误/警告。因为这些警告不会影响恢复过程。

（注意：我尝试过，PIVOTAL的文档中也提到了该问题）
