不要你看到的问题与嵌套''' ？ – karthikr

我的猜测是之前有一个'||'丢失。或':: timestamp without time zone'应该在它之前的引号内。顺便说一句：我不喜欢在规则中放入db_link的_idea_。也许我太老套了。 – wildplasser

@karthikr 我不知道我是否明白你的观点是否正确......我编辑了上述编码..但是我仍然收到错误 – Abdul

不知道的想法，在规则中使用DBLINK（未测试）。但是，你有一个封闭)太多：

CREATE OR REPLACE RULE INSERT_part_name AS 
ON INSERT TO partition.part_name 
DO INSTEAD SELECT crm.dblink_exec('crm_server'::text, 
    'insert into partition.part_name(customerid, partition_name, partition, createdate) 
    values(' || new.customerid || ',' || quote_literal(new.partition_name) || ',false' 
    || ',' || quote_literal(new.createdate::timestamp without time zone));

我会用format()，不过，对于更清洁的代码（需要Postgres的9.1+）：

CREATE OR REPLACE RULE INSERT_part_name AS 
ON INSERT TO partition.part_name 
DO INSTEAD SELECT crm.dblink_exec('crm_server'::text, format(
'INSERT INTO partition.part_name(customerid, partition_name, partition, createdate) 
    VALUES(%s, %L, false, %L)' 
,NEW.customerid, NEW.partition_name, NEW.createdate::timestamp));
