Technically, yes. You can create a Rule and then bind the rule to different columns.
However, constraints are the perferred mechanism and it does require that you specify them each time.

I want to define a constraint check at the top of the procedure, and use it inside the different CREATE TABLE loops, or, in other words, I only want to define a phone number constraint once. I do not want to have to cut/past/rename it each time etc.. None of the documentation I have access to shows syntax to do this.
