The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/14/collation.html
Description:
This page should include a link to the Collation docs for the Unicode Locale
Data Markup Language (LDML).
http://www.unicode.org/reports/tr35/tr35-collation.html#Collation_Settings
If one wants to create a custom collation e.g. de-DE-u-kn-true, only there
are all possible value for creating customized collations.
Kind regards
