Postgresql COPY CSV 错误：最后一个预期列后有额外数据

我正在尝试从以下位置导入数据http://www.unitedstateszipcodes.org/zip-code-database http://www.unitedstateszipcodes.org/zip-code-database。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","UNIQUE","Holtsville",,"Irs Service Center","NY","Suffolk County","America/New_York","631","40.81","-73.04","NA","US","0","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;

结果是这样的：

ERROR: extra data after last expected column
SQL state: 22P04
Context: COPY zip_codes, line 2: ""00501","UNIQUE","Holtsville",,"I R S Service Center","NY","Suffolk County","America/New_York","631"..."

我在导入时做错了什么？

就像魅力一样，在这里......

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 ','
        ;

Result:

DROP TABLE
CREATE TABLE
COPY 42522

（也许OP有CR/CRLF问题？）
