That doesn't look like an ICU locale. You may mean "nb-NO-x-icu". But
otherwise, yes.
 
 
Ok, is there a way I can get a list of ICU-collations?

If you did initdb with a version with ICU support, the ICU collations
should be there.

Only if you didn't define the column with a per-column collation initially.
 
Ok, thanks.
 
Looking forward to this being a per-database setting so it's (hopefully) more
transparent.
