我需要一些有关 Postgres 备份的帮助。我正在尝试从 Windows 7 x32 的 pgAdmin III 1.16.1 恢复数据库备份。原始数据库位于一台服务器（也是 w7）中，另一台位于 Ububtu 服务器上。我已经尝试了所有可用选项的组合，我什至尝试从服务器的命令行和 Windows 进行备份和恢复，而不是使用图形界面。

这些是执行的命令和错误。结果是数据库恢复了，但只恢复了一部分。

请帮我！

我只复制了日志的一部分，因为它太长了......但没有错误接缝是“那个”

C:\Program Files\pgAdmin III\1.10\pg_dump.exe --host 00.00.0.000
--port 0000 --username "username" --role "role" --no-password  
--format tar --blobs --encoding UTF8 --verbose --file 
 "C:\Users\xxxxx\Documents\BackUpPostgres\backU.backup" "DATABASE"

C:\Program Files\pgAdmin III\1.10\pg_restore.exe --host 111.111.11.111 
 --port 0000 --username "username" --dbname "database"
 --role "role" --no-password  --verbose  
 "C:\Users\xxxxx\Documents\BackUpPostgres\backU.backup"

您应该在没有架构的情况下转储数据public，可以使用--exclude-schema开关（或快捷方式是-N）来完成。

pg_dump -U my_user -d my_database -N public -F c backup.dump
