We will still allow the ICU format locale IDs for input; we would just convert them to BCP47 before storing them in the catalog. And there's an inverse function, so it's easy enough to offer a view that shows the ICU format locale IDs in addition to the BCP 47 tags. I don't think it's hugely important that we use BCP47; ICU format locale IDs would also make sense. But I do think we should be consistent to simplify things where we can -- collator versioning is hard enough without wondering how a user-entered string will be interpreted. And if we're going to be consistent, BCP 47 seems like the most obvious choice. -- Jeff Davis PostgreSQL Contributor Team - AWS
