Mysql 如何在postgresql中Rexep拆分后插入新行

我有一张这样的桌子，在这个问题上：

我想在拆分行之后插入新行。如何在postgresql中实现这一点？我可以使用

SELECT "ID", 
regexp_split_to_table("Cars", '(([,;] (?!damaged))|[,;]? and )') "Cars" 
FROM mytable;

但是我不知道如何修改表格

begin;

create temporary table mytable_temp after commit drop as
-- Here is SQL you povided so no any questions about it to me :)
SELECT "ID", 
regexp_split_to_table("Cars", '(([,;] (?!damaged))|[,;]? and )') "Cars" 
FROM mytable;

-- Here we will deal with fake table instead of your original table
-- to prevent data lost

create mytable_new as
select * from mytable_temp;

commit;

检查是否

mytable\u new

包含正确的数据，然后

-- truncate mytable;
-- insert into mytable select * from mytable_new;
-- drop table mytable_new;

---

在哪里插入行？
