The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/15/collation.html Description:
This page states: Observe how in the traditional ICU locale naming system, the root locale is selected by an empty string. CREATE COLLATION latinlast (provider = icu, locale = 'en-u-kr-grek-latn'); CREATE COLLATION latinlast (provider = icu, locale = 'en@colReorder=grek-latn'); Neither of the locales are empty strings.
