database – Postgresql COPY CSV ERROR：上一个预期列之后的额外数据

我正在尝试从 http://www.unitedstateszipcodes.org/zip-code-database导入数据.数据的子集如下所示：

"zip","type","primary_city","acceptable_cities","unacceptable_cities","state","county","timezone","area_codes","latitude","longitude","world_reg$
"00501","UNIQUE","Holtsville","I R S Service Center","NY","Suffolk County","America/New_York","631","40.81","-73.04","NA","US","0","384","00544","irs Service Center","0"

我运行的postgresql命令是这样的：

copy development.zip_codes FROM '/tmp/zip_code_database.csv' WITH DELIMITER ',' CSV HEADER;

结果如下：

ERROR: extra data after last expected column
sql state: 22P04
Context: copY zip_codes,line 2: ""00501","631"..."

我输入的错误是什么？

像魅力一样,这里……

DROP TABLE zipcodes CASCADE;
CREATE TABLE zipcodes
        ( id serial NOT NULL PRIMARY KEY,zzip varchar NOT NULL UNIQUE,ztype varchar,primary_city varchar,acceptable_cities varchar,unacceptable_cities varchar,state varchar,county varchar,ztimezone varchar,area_codes varchar,latitude varchar,longitude varchar,world_region varchar,country varchar,decommissioned varchar,estimated_population varchar,notes varchar
        ); 

copY zipcodes (zzip,ztype,primary_city,acceptable_cities,unacceptable_cities,state,county,ztimezone,area_codes,latitude,longitude,world_region,country,decommissioned,estimated_population,notes )
FROM '/tmp/zip_code_database.csv'
        WITH CSV HEADER delimiter ','
        ;

结果：

DROP TABLE
CREATE TABLE
copY 42522

(也许OP有CR / CRLF问题？)
