I don't really know if this is necessary anyway. Just create the
collations with the names that the operating system presents. There is
no requirement to make the names match POSIX.

If you want to make them match POSIX for some reason, you can also just
change the object name but leave the collcollate/collctype fields the
way they came from the OS.
