如何通过COPY Command把s3上csv gz的文件load到reshift上

[alex_82712]

csv gz的文件是以逗号分隔的，但是有一些特殊字符为了保证数据的完整性，被双型号包起来了

csv file sample:

doc_key,doc_name,doc_brand,brand_inc,etl_load_date
8a14eff760993c84d2306b3547fc6bea,VIRTUALLY CALIFORNIA,UNITED STATES OF AMERICA,UNKNOWN,2018-02-28
1fd23373942c9ffcdfc7223cd1114ee1,"ARIZONA \"9\" LLC",UNITED STATES OF AMERICA,UNKNOWN,2018-02-28

copy stg.train_ticket from 's3://{path}/'
CREDENTIALS 'aws_access_key_id={aws_access_key_id};aws_secret_access_key={aws_secret_access_key}'
TRIMBLANKS TRUNCATECOLUMNS ACCEPTINVCHARS dateformat as 'auto'
GZIP csv quote as '"' delimiter ',' IGNOREHEADER as 1;

我在sqlworkbench运行上面这个copy cmd，报错
An error occurred when executing the SQL command:
copy stg.train_ticket from 's3://{path}/'
CREDENTIALS 'aws_access_key_id={aws_access_key_id};aws_secret_access...

[Amazon](500310) Invalid operation: Load into table 'train_ticket ' failed. Check 'stl_load_errors' system table for details.;
1 statement failed.

查到stl_load_errors这个表的错误信息是：
column: doc_name
err_reason: Invalid quote formatting for CSV
raw_field_value: ARIZONA \\
err_code: 1214

请问这一段要怎么处理 "ARIZONA \"9\" LLC"
