There is a difference in string comparison between alpine and normal versions

[Ihor Dotsenko]

Ran into #851 using postgres:16.1-alpine

In README.md it's said:

Also of note, Alpine-based variants starting with Postgres 15 support ICU locales. Previous Postgres versions based on alpine do not support locales; see "Character sets and locale" in the musl documentation for more details.

As far as I understand, now it should be possible to build the alpine-based image with the correct en-US.UTF-8 collation and have proper string comparison. Or do I miss anything?

I mean that would be cool to have the same behaviour out of the box for both alpine- and debian-based images.
