Would we be the first major database to support custom collation rules?

Two quick comments:
- pg_dump support need to be added for CREATE COLLATION / DATABASE
- there doesn't seem to be a way to add rules to template1.
If someone wants to have icu rules and initial contents to their new

Thanks. I played some more with it, and still are still some missing
odds and ends:
- There is a new option ICU_RULES to CREATE DATABASE, but it is not
reflected in \h CREATE DATABASE.
atch with this fixed.

I like that patch. It applies and passes regression tests.
I played with it:

The patch does not apply on top of HEAD as in [1], please post a rebased patch:

The code is pretty straightforward. It mainly just records these rules
in the catalog and feeds them to ICU when creating the collator object.
