PgAdmin 将文本列导出到 csv 文件

如何解决PgAdmin 将文本列导出到 csv 文件

我有一个包含 3 列的表格 - 类型、名称和代码。 code 列包含过程/函数源代码。 我已使用 Import/Export 中的 PgAdmin 4 v5 选项将其导出到 csv 文件，但 code 列不坚持 csv 文件中的单个单元格。其中的数据分布在许多行和列中。 我已检查 Encoding 为 UTF8，它在导出其他表时正常工作。

其他设置：Format: csv、Encoding: UTF8。没有更改任何其他设置

有人可以帮助如何正确导出它。

解决方法

对所见内容的解释：

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','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,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
