如何在postgresql中存储多语言字符串？

这个问题并非如下：

1. Best way to store images in PostgreSQL [duplicate]
2. How to design a database schema for storing text in multiple languages?
3. Best practise for storing multilingual strings

我希望在一个表格中插入日语，韩语，中文（简体和繁体）和俄语字符的字符串。

INSERT INTO articles (title, text, date)
VALUES ('article title', 'Long text with chinese (龙), korean(울), japanese(形) and russian(ЯД) characters', '2017-02-16');

如何在Postgresql中使用正确的LC_COLLATE和LC_CTYPE为表中的多语言字符串创建数据库？

CREATE DATABASE "articles"
       WITH OWNER "postgres"
       ENCODING 'UTF8'
       LC_COLLATE = 'zh_CN.UTF-8'
       LC_CTYPE = 'zh_CN.UTF-8'
       TEMPLATE = template0;

OR

CREATE DATABASE "articles"
       WITH OWNER "postgres"
       ENCODING 'UTF8'
       LC_COLLATE = 'zh_TW.UTF-8'
       LC_CTYPE = 'zh_TW.UTF-8'
       TEMPLATE = template0;

OR

CREATE DATABASE "articles"
       WITH OWNER "postgres"
       ENCODING 'UTF8'
       LC_COLLATE = 'ko_KR.UTF-8'
       LC_CTYPE = 'ko_KR.UTF-8'
       TEMPLATE = template0;

OR

CREATE DATABASE "articles"
       WITH OWNER "postgres"
       ENCODING 'UTF8'
       LC_COLLATE = 'ja_JP.UTF-8'
       LC_CTYPE = 'ja_JP.UTF-8'
       TEMPLATE = template0;

OR

CREATE DATABASE "articles"
       WITH OWNER "postgres"
       ENCODING 'UTF8'
       LC_COLLATE = 'ru_RU.UTF-8'
       LC_CTYPE = 'ru_RU.UTF-8'
       TEMPLATE = template0;
