我试图使用Knex-Seed-File的Knex模块从NodeJS应用程序向Postgres表中插入一行。
每次尝试时，我只收到一个列/字段的错误，这是一个多维文本数组：photo_urls text[][] NULL,。该错误表明存在格式错误的数组文字。
完成official Postgres documentation后，我尝试使用双引号：
（ 8.14.2。数组值输入）
“要将数组值写为文字常量，请将元素值括在花括号中并用逗号分隔...您可以在任何元素值周围加上双引号，如果它包含逗号或花括号，则必须这样做。“
我也尝试使用 ARRAY构造函数语法。
以下是我在构造输入时所做的各种尝试，以及作为实际生成的SQL和返回的错误返回的内容：

据报道，与knex postgres集成有关的许多错误/问题： #658，#828，#869，#1602，......似乎已关闭和/或合并到#1661。
据我所知，问题似乎已经解决了。
任何人都可以帮助确定我做错了什么或我可以做些什么来解决问题？

该模块现已升级（0.3.1），现在应该正确处理数组。要在更新包后输入数组值，应使用以下模式：
[["ext_profile:","ext_random:","int_random:"],["https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=Ext+Profile","https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=Ext+Random+1,https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=Ext+Random+2","https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=Int+Random+1,https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=In+Random+2,https://dummyimage.com/300x250/0cb3f5/fcfcfc.png&text=Int+Random+3"]]

@touko正确识别出该问题是csv文件默认行为的结果。
保存csv文件时，双引号会添加到包含逗号或双引号字符的任何内容中。
这些帖子和文章对此进行了解释：
关于knex-seed-file模块，在Github中打开了issue。目前，我正在使用在文本编辑器中打开csv文件并手动删除不需要的双引号的解决方法。
示例（注意：我使用的是管道分隔的csv文件）：
