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](locale.md) and [Section 23.2](collation.md). 
-  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](multibyte.md).
