How to insert multiline text into a column of the PostgreSQL table?

I’m looking for a way to insert a multiline text into PostgreSQL table (column).

Suppose I have a table ‘problem’ within the data.sql file, and I want to insert a multiline text into DETAILS column.
What should I do?

>Solution :

You can use String Constants With C-Style Escapes by adding an E before the text constant, then an \n wherever you want a newline: demo

create table test(id serial primary key, a text);
insert into test (a) values (E'line1\nline2\nline3') returning *;
