Hi everyone,

like the others before me we (the university of Münster) are happy to
see this feature as well. Thank you this.

When I applied the patch two weeks ago I run into the issue that initdb
did not recognize the new parameters (collation-provider and icu-locale)
but I guess it was caused by my own stupidity.

I am able to recreate the issue described by Daniel on my machine.

Now it works as expected. I just had to update the patch since commit
3f6b3be3 had modified two lines which resulted in conflicts. You find
the updated patch as attachement to this mail.


Best regards,

Marius Timmer
