Code review comment for lp:~jpds/launchpad/fix_361650

I don't much like the column name either, but it does match the domain language used at http://www.ubuntu.com/getubuntu/mirror/1 so I guess it is correct.

Why are we limiting things to one official country mirror per country? Is there a technical issue we need to ensure doesn't happen, or is this an arbitrary choice made by us or the mirror maintainers?

Patch number is patch-2207-23-0.sql. Its good to land if you can confirm that the UNIQUE constraints are actually desirable.
