With integrity constraints, you have to know when you stop :-) Not
everything can be declared in SQL (I'm still searching for a way to
have a trigger fire at the end of a *transaction*, in order to check
cross-table integrity), so no check is perfect. I just wanted to catch
the majority of the mistakes that people can do when they type phone
numbers, not all of them.

Many thanks to all for the advices (and to Oliver for the Debian
package since this is the one I use).
