How can I add a new language localization(locale) support

[eetemadi]

hello,
I want to add the Locale Support for my language (Farsi) in this database.
I found that the postgresql have a good support for Unicode and also,
Unicode character support, in my language.
But some ordering and sorting changes are necessary.
Documents says that there is some collation order function that we can
define our custom collation order for alphabetic sorting.
Where I can found it, What document can help me, Where is this function?
Is there any document that can help me for implementing all localization
support in my language?

with thanks and regards.

What you need to fix your ordering issues is a new locale definition
that sorts the way you want. The Postgres docs won't help you with
that; you'll need to go find some documentation about how libc works
with locales.

If you want to develop a set of localized Postgres error messages,
we do have some documentation about how to do that --- see the "Native
Language Support" chapter in the "Internals" section.
