\d+ {table_name}
未显示详细分区&分发关键信息。
我猜可能有一些配置参数尚未设置,因为之前它显示完美。
默认情况下,它先前显示该表/ etc的所有子表/分发键。

如果\ d +会显示您的分配键;然后,您可以使用下面提到的查询来显示分配密钥。
从gp_distribution_policy中选择* where localoid =(从pg_class中选择oid,其中relname ='My_table_name');

我敢打赌你有两个表名相同,一个在公共模式中,另一个在不同模式中。如果您没有指定模式名称,Greenplum(如PostgreSQL)将在搜索路径中列出的模式中搜索表名。将显示基于search_path顺序的第一个匹配项。
注意我没有指定架构名称,只是" \ d store_sales"但是列出的表是" public.store_sales"?它由我的search_path确定。
gpdb=# \d store_sales

我知道这里有什么错误
如果您检查DDL或从其他服务器(不是直接GP群集)转储任何表(使用pg_dump),其中客户端已安装并且已授予GP服务器连接,则通过\ d,\ d +或pg_dump生成DDL,你不会得到分发类 我刚试过分区表,分区类也会丢失。
同时如果您从psql提示符@ GP主服务器尝试\ d,\ d +或pg_dump 您将在表
的生成DDL中获得分发和分区类您还可以尝试生成外部表格的DDL 从ETL服务器或安装GP客户端的任何其他服务器,从此psql提示符,您将不会获得Location类。
试试这个并恢复

如果您没有使用greenplum提供的psql,则不会显示“greenplum feature”。请检查您是否使用了正确的psql。
