I hope you do. I think that we'd realize significant benefits by
having ICU become the defacto standard collation provider, that most
users get without even realizing it. As things stand, you have to make
a point of specifying an ICU collation as your per-column collation
within every CREATE TABLE. That's a significant barrier to adoption.

I strongly prefer the second approach. The only downside that occurs
to me is that that approach requires more code. Is there something
that I've missed?
