Hello Kyotaro Horiguchi,

i still think this a bug, because "createdb" also can't use any ICU-collati=
ons (same error message).

On Windows Server 2016/2019/2022 and Windows 10/11 the ICU-Options work as =
expected!
Why does the problem only occurs on Windows Server 2012?

An Upgrade to PostgreSQL 15 is not an option, now.

Best Regards,
Stefan.

If you are unfortunately using PostgreSQL 10, it doesn't support ICU collat=
ions as the default for databases.  It's a new feature of 15.

https://www.postgresql.org/docs/15/release-15.html

If you are using PG15, --icu-locale accompanied by --locale-provider=3Dicu =
instead of --locale will work for you.

https://www.postgresql.org/docs/devel/app-initdb.html
