+ The nature of some locale categories is that their value has to be
+ fixed for the lifetime of a database cluster. That is, once

+ <literal>LC_COLLATE</literal> and <literal>LC_CTYPE</literal> are

+ must be kept fixed, or indexes on text columns will become corrupt.
+ <productname>PostgreSQL</productname> enforces this by recording

+ serve as defaults when the server is started. If you delete the

Note that the locale behavior of the server is determined by the
environment variables seen by the server, not by the environment
- of any client. Therefore, be careful to set these variables
+ of any client. Therefore, be careful to configure the correct locale settings
before starting the server. A consequence of this is that if
client and server are set up to different locales, messages may
appear in different languages depending on where they originated.
</para>
+ <note>
+ <para>
+ When we speak of inheriting the locale from the execution
+ environment, this means the following on most operating systems:
+ For a given locale category, say the collation, the following
+ environment variables are consulted in this order until one is
+ found to be set: <envar>LC_ALL</envar>, <envar>LC_COLLATE</envar>
+ (the variable corresponding to the respective category),
+ <envar>LANG</envar>. If none of these environment variables are
+ set then the locale defaults to <literal>C</literal>.

+ Some message localization libraries also look at the environment
+ variable <envar>LANGUAGE</envar> which overrides all other locale
+ settings for the purpose of setting the language of messages. If
