   This chapter describes the available localization features from the
   point of view of the administrator. PostgreSQL supports two
   localization facilities:
     * Using the locale features of the operating system to provide
       locale-specific collation order, number formatting, translated
       messages, and other aspects. This is covered in Section 23.1 and
       Section 23.2.
     * Providing a number of different character sets to support storing
       text in all kinds of languages, and providing character set
       translation between client and server. This is covered in
       Section 23.3.
