<span class="productname">PostgreSQL</span> supports two localization
facilities:
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
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 <a class="xref" href="locale.html" title="23.1. Locale Support">Section 23.1</a> and
<a class="xref" href="collation.html" title="23.2. Collation Support">Section 23.2</a>.
