pgpointcloud备份由于缺少关联而失败

Question

我正在尝试仅备份点云的架构，我尝试使用pgadmin4中的内置备份，并且收到以下错误。它抱怨ERROR: relation "pointcloud_formats" does not exist我测试了select schema, srid from pointcloud_formats where pcid = 1查询，并且返回没有问题。有什么想法吗？

pg_dump: Dumping the contents of table "pc_0201507091159" failed: PQgetResult() failed.
pg_dump: Error message from server: ERROR:  relation "pointcloud_formats" does not exist
LINE 1: select schema, srid from pointcloud_formats where pcid = 1
                                 ^
QUERY:  select schema, srid from pointcloud_formats where pcid = 1
pg_dump: The command was: COPY pointcloud_99_526.pc_0201507091159 (id, pa) TO stdout;
