Yeah. My recommendation is just LOCALE:

regression=# CREATE DATABASE test1 TEMPLATE=template0 ENCODING = 'UTF8' LOCALE = 'C';
CREATE DATABASE
regression=# CREATE DATABASE test2 TEMPLATE=template0 ENCODING = 'UTF8' ICU_LOCALE = 'C';
NOTICE: using standard form "en-US-u-va-posix" for locale "C"
CREATE DATABASE

I think it's probably intentional that ICU_LOCALE is stricter
about being given a real ICU locale name, but I didn't write
any of that code.
