I second that.  Most people don't pay attention to that when creating a
cluster, so having a locale-agnostic collation is often better than
inheriting whatever default happened to be set in your shell.
For example, the Debian/Ubuntu binary packages create a cluster when
you install the server package, and most people just go on using that.
