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.

If you are unfortunately using PostgreSQL 10, it doesn't support ICU collations as the default for databases. It's a new feature of 15. https://www.postgresql.org/docs/15/release-15.html > - Allow ICU collations to be set as the default for clusters and > databases (Peter Eisentraut) > Previously, ICU collations could only be specified in CREATE > COLLATION and used with the COLLATE clause. If you are using PG15, --icu-locale accompanied by --locale-provider=icu instead of --locale will work for you. https://www.postgresql.org/docs/devel/app-initdb.html > Alternatively, the ICU library can be used to provide locale services. > (Again, this only sets the default for subsequently created > databases.)

Should we then use default-collation "de" instead of "de-x-icu" or "German_Germany.1252" or could this cause problems later when upgrading to PostgreSQL 15 or 16 and using "de-x-icu" as default-collation?

Oh, it might also be that ancient Windows can also understand "de-DE" or "de" too, but not "de-x-icu"? That "de-x-icu" name is an internal PostgreSQL convention for collation identifiers and shouldn't be passed to initdb. If that's the case it might just be that the ICU-based versions of Windows are more tolerant, and interpret "de-x-icu" as "de", ignoring the rest, but the ancient versions reject it? (I have no access to old Windows, I just read that even Vista could understand de-DE type names, formally known as BCP47, in some contexts... it just wasn't using ICU yet). ^ permalink raw reply [nested|flat] 2+ messages in thread
