+dnl Verify that the version of the pkg-config macros are at least

+dnl of pkg.m4 when generating configure.
+dnl
+dnl To ensure that this macro is defined, also add:
+dnl m4_ifndef([PKG_PREREQ],
+dnl [m4_fatal([must install pkg-config 0.29 or later before running autoconf/autogen])])

+dnl of the macros you require.

+ A collation is an SQL schema object that maps an SQL name to locales
+ provided by libraries installed in the operating system. A collation
+ definition has a <firstterm>provider</firstterm> that specifies which
+ library supplies the locale data. One standard provider name
+ is <literal>libc</literal>, which uses the locales provided by the
+ operating system C library. These are the locales that most tools

+ A collation object provided by <literal>libc</literal> maps to a

+ settings. (As
the name would suggest, the main purpose of a collation is to set
<symbol>LC_COLLATE</symbol>, which controls the sort order. But
it is rarely necessary in practice to have an
<symbol>LC_CTYPE</symbol> setting that is different from
<symbol>LC_COLLATE</symbol>, so it is more convenient to collect
these under one concept than to create another infrastructure for
- setting <symbol>LC_CTYPE</symbol> per expression.) Also, a collation

is tied to a character set encoding (see <xref linkend="multibyte">).

</para>
+ <para>
+ A collation provided by <literal>icu</literal> maps to a named collator

<para>
On all platforms, the collations named <literal>default</>,

If the operating system provides support for using multiple locales
within a single program (<function>newlocale</> and related functions),

then when a database cluster is initialized, <command>initdb</command>
populates the system catalog <literal>pg_collation</literal> with
collations based on all the locales it finds on the operating

+ <title>libc collations</title>
+
+ <para>
+ For example, the operating system might

- In case a collation is needed that has different values for

Use of the stripped collation names is recommended, since it will
make one less thing you need to change if you decide to change to
another database encoding. Note however that the <literal>default</>,

- regardless of the database encoding.

collations have identical behaviors. Mixing stripped and non-stripped
collation names is therefore not recommended.

+ <title>ICU collations</title>
+
+ <para>
+ Collations provided by ICU are created with names in BCP 47 language tag
+ format, with a <quote>private use</quote>
+ extension <literal>-x-icu</literal> appended, to distinguish them from
+ libc locales. So <literal>de-x-icu</literal> would be an example.
+ </para>
+
+ <para>
+ With ICU, it is not sensible to enumerate all possible locale names. ICU
+ uses a particular naming system for locales, but there are many more ways
+ to name a locale than there are actually distinct locales. (In fact, any
+ string will be accepted as a locale name.)
+ See <ulink url="http://userguide.icu-project.org/locale"></ulink> for
+ information on ICU locale naming. <command>initdb</command> uses the ICU
+ APIs to extract a set of locales with distinct collation rules to populate
+ the initial set of collations. Here are some examples collations that

+ When using collations provided by the ICU library, the ICU-specific version
+ of the collator is recorded in the system catalog when the collation object
+ is created. When the collation is then used, the current version is
+ checked against the recorded version, and a warning is issued when there is
+ a mismatch, for example:
+<screen>
+WARNING: ICU collator version mismatch
+DETAIL: The database was created using version 1.2.3.4, the library provides version 2.3.4.5.
+HINT: Rebuild all objects affected by this collation and run ALTER COLLATION pg_catalog."xx-x-icu" REFRESH VERSION, or build PostgreSQL with the right version of ICU.
+</screen>
+ A change in collation definitions can lead to corrupt indexes and other
+ problems where the database system relies on stored objects having a
+ certain sort order. Generally, this should be avoided, but it can happen
+ in legitimate circumstances, such as when
+ using <command>pg_upgrade</command> to upgrade to server binaries linked
+ with a newer version of ICU. When this happens, all objects depending on
+ the collation should be rebuilt, for example,
+ using <command>REINDEX</command>. When that is done, the collation version
+ can be refreshed using the command <literal>ALTER COLLATION ... REFRESH
+ VERSION</literal>. This will update the system catalog to record the
+ current collator version and will make the warning go away. Note that this
+ does not actually check whether all affected objects have been rebuilt
+ correctly.
+ </para>

+ database that need to be refreshed and the objects that depend on them:
