libicu global support

Hi,

during the adoption of Centos 8 on our servers we ran into problems with
Postgresql (13.3), glibc (delivered by the Centos) and performance of
sorting. Because of that we're planning to use the ICU collations
(en-x-icu), but the current implementation is quite complicated to adopt as
there isn't support of global setup per cluster (initdb) nor creating of
database.

So, my silly question: is there any chance a work can be done on it with a
new version anytime soon?

There were already some discussions around some time ago:

Thank you,
