PgAdmin Exporting text column to csv file - postgresql

Question

I have a table with 3 columns - type, name, and code.
The code column contains the procedure/function source code.
I have exported it to a csv file using Import/Export option in PgAdmin 4 v5, but the code column does not stick to a single cell in the csv file. The data in it spreads across to many of the rows and columns.
I have checked Encoding as UTF8 which works fine normally while exporting other tables.
Other settings: Format: csv, Encoding: UTF8. Have not changed any other settings
Can someone help how to export it properly.

An explanation of what you are seeing:
CREATE TABLE public.csv_test (
fld_1 character varying,
fld_2 character varying,
fld_3 character varying,
fld_4 character varying
);
insert into csv_test values ('1', E'line with line end. \n New line', 'test', 'dog');
insert into csv_test values ('2', E'line with line end. \n New line', 'test', 'dog');
insert into csv_test values ('3', E'line with line end. \n New line \n Another line', 'test2', 'cat');
insert into csv_test values ('4', E'line with line end. \n New line \n \t Another line', 'test3', 'cat');
select * from csv_test ;
fld_1 | fld_2 | fld_3 | fld_4
-------+-----------------------+-------+-------
1 | line with line end. +| test | dog
| New line | |
2 | line with line end. +| test | dog
| New line | |
3 | line with line end. +| test2 | cat
| New line +| |
| Another line | |
4 | line with line end. +| test3 | cat
| New line +| |
| Another line | |
\copy csv_test to csv_test.csv with (format 'csv');
\copy csv_test to csv_test.txt;
--fld_2 has line ends and/or tabs so in CSV the data will wrap inside the quotes.
cat csv_test.csv
1,"line with line end.
New line",test,dog
2,"line with line end.
New line",test,dog
3,"line with line end.
New line
Another line",test2,cat
4,"line with line end.
New line
Another line",test3,cat
-- In text format the line ends and tabs are shown and not wrapped.
cat csv_test.txt
1 line with line end. \n New line test dog
2 line with line end. \n New line test dog
3 line with line end. \n New line \n Another line test2 cat
4 line with line end. \n New line \n \t Another line test3 cat
