Isn't this pretty much what adopting ICU is supposed to give us? OS-independent 

I'd be interested in seeing the rest data for this performance report, partly 
as I'd like to see how ICU collations would compare when ICU is crudely hacked 
into place for testing.

I think of a new idea.
Add a compare method column to pg_collation.
Every collation has its own compare function or null.
When function varstr_cmp is called, if specified collation
has compare function, call it instead of strcoll().

How about this?
