Allow the <link linkend="configure"><acronym>ICU</></> library to optionally be used for collation support (Peter

New major version numbering (Peter Eisentraut, Tom Lane)

</para>

<para>

The <acronym>ICU</> library has versioning that allows detection of collation

changes between versions. It is enabled via configure option

<option>--with-icu</>. The default still uses the operating system's native

collation library.

Major versions will now increase just the first number, and minor

releases will increase just the second number. A third number will no

longer be used in Postgres version numbers.
