Postgresql 如何使用pgadmin 4备份表？

我尝试了右键单击表格时弹出的“备份”菜单中的多种设置，但都没有导致备份表格的任何数据。生成的文件约为5k，但此表有近2M行，大小可能为数百兆字节

我想备份此表，以便在对生产系统执行某些清理查询之前将其还原到测试数据库

“流程详细信息”窗口显示一系列命令，但未显示任何错误：

/Applications/pgAdmin 4.app/Contents/SharedSupport/pg_dump --file "/Users/xxx/device_status_2m" --host "myhostname" --port "5432" --username "postgres" --no-password --verbose --format=c --blobs --table "public.status" "mydatabasename"

---

结果表明，pg_转储对于时间刻度超表不能正常工作。Timescale建议采用这种方法：
