PostgreSQL version: 9.2.0
Operating system: Windows Vista 32-bit
Description:

I'm using the "postgresql-9.2.0-1-windows.exe" installer, from Enterprise
DB.

With the GUI installer, I chose the locale "English, New Zealand". This is
correctly maintained in initcluster.vbs, which executes the command:

"C:\Program Files\PostgreSQL\9.2\bin\initdb.exe" --pwfile "C:\Program
Files\PostgreSQL\9.2\radE202E.tmp" --locale="English, New Zealand"
--encoding=UTF-8 -A md5 -U postgres -D "C:\Program
Files\PostgreSQL\9.2\data"

But the output from this command show:

The database cluster will be initialized with locale "English_United
States.1252".
The default text search configuration will be set to "english".
