在PostgreSQL中更新远程表（保持fks）

Question

I am using pgAdmin III at my work and postgresql at work and at the remote hosting server (webfaction). Through Putty I am creating a tunnel for pgAdmin to work with my local and my remote databases. I have a table which primary key is referenced by other tables' keys (as a foreign key).

What is the best way to update that remote table with the values I have on my local table?

What I (unsuccessfully) try to do is 'backup' my local table and then try to 'restore' my remote table with that file. However, pgAdmin III gives me duplicate key value error.

pg_restore: connecting to database for restore
pg_restore: restoring data for table "main_city"
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 1972; 0 17110 TABLE DATA main_city user
pg_restore: [archiver (db)] COPY failed: ERROR:  duplicate key value violates unique constraint "main_city_pkey"
CONTEXT:  COPY main_city, line 1: "1    London  20  30  4   1"
pg_restore: setting owner and privileges for TABLE DATA main_city
WARNING: errors ignored on restore: 1

Process returned exit code 1.

Shall I try another postgresql client? It is a pain if I try to remove all those references and try to update manually. Any help would be appreciated!

我对pgAdmin一无所知，但是如何将文件中的数据添加到临时表中以及如何根据行是否存在将其更新/插入到原始表中呢？
