"extra data after last expected column" while trying to import a csv file into postgresql

I try to copy the content of a CSV file into my postgresql db and I get this error "extra data after last expected column".

The content of my CSV is

    agency_id,agency_name,agency_url,agency_timezone,agency_lang,agency_phone
100,RATP (100),http://www.ratp.fr/,CET,,

and my postgresql command is

COPY agency (agency_name, agency_url, agency_timezone) FROM 'myFile.txt' CSV HEADER DELIMITER ',';

Here is my table

CREATE TABLE agency (
    agency_id character varying,
    agency_name character varying NOT NULL,
    agency_url character varying NOT NULL,
    agency_timezone character varying NOT NULL,
    agency_lang character varying,
    agency_phone character varying,
    agency_fare_url character varying
);

     Column      |       Type        | Modifiers 
-----------------+-------------------+-----------
 agency_id       | character varying | 
 agency_name     | character varying | not null
 agency_url      | character varying | not null
 agency_timezone | character varying | not null
 agency_lang     | character varying | 
 agency_phone    | character varying | 
 agency_fare_url | character varying | 

Now you have 7 fields.

You need to map those 6 fields from the CSV into 6 fields into the table.

You cannot map only 3 fields from csv when you have it 6 like you do in:

\COPY agency (agency_name, agency_url, agency_timezone) FROM 'myFile.txt' CSV HEADER DELIMITER ',';

All fields from the csv file need to to be mapped in the copy from command.

And since you defined csv , delimiter is default, you don't need to put it.
