首先安装dblink

然后，你可以这样做:

INSERT INTO t2 select * from 
dblink('host=1.2.3.4
 user=*****
 password=******
 dbname=D1', 'select * t1') tt(
       id int,
  col_1 character varying,
  col_2 character varying,
  col_3 int,
  col_4 varchar 
);

您还可以使用pgAdmin II中的备份功能。只需遵循以下步骤:

In pgAdmin, right click the table you want to move, select "Backup" Pick the directory for the output file and set Format to "plain" Click the "Dump Options #1" tab, check "Only data" or "only Schema" (depending on what you are doing) Under the Queries section, click "Use Column Inserts" and "User Insert Commands". Click the "Backup" button. This outputs to a .backup file Open this new file using notepad. You will see the insert scripts needed for the table/data. Copy and paste these into the new database sql page in pgAdmin. Run as pgScript - Query->Execute as pgScript F6

工作良好，可以做多个表在一个时间。

如果你在Windows上运行pgAdmin(备份:pg_dump，恢复:pg_restore)，默认情况下，它会尝试将文件输出到c:\Windows\System32，这就是为什么你会得到拒绝权限/访问的错误，而不是因为用户postgres不够高。以管理员身份运行pgAdmin，或者直接选择Windows系统文件夹以外的输出位置。

首先安装dblink

然后，你可以这样做:

INSERT INTO t2 select * from 
dblink('host=1.2.3.4
 user=*****
 password=******
 dbname=D1', 'select * t1') tt(
       id int,
  col_1 character varying,
  col_2 character varying,
  col_3 int,
  col_4 varchar 
);

如果你想将数据从一个服务器数据库复制到另一个服务器数据库，那么你必须创建dblink连接两个数据库，否则你可以导出CSV中的表数据，并导入其他数据库表中的数据，表字段应该与主表相同。

检查这个python脚本

python db_copy_table.py "host=192.168.1.1 port=5432 user=admin password=admin dbname=mydb" "host=localhost port=5432 user=admin password=admin dbname=mydb" alarmrules -w "WHERE id=19" -v
Source number of rows = 2
INSERT INTO alarmrules (id,login,notifybyemail,notifybysms) VALUES (19,'mister1',true,false);
INSERT INTO alarmrules (id,login,notifybyemail,notifybysms) VALUES (19,'mister2',true,false);
