atttypmod would be a natural place for that stuff, if you can fit it
into 31 bits. The bigger problem is how are you going to get
type-specific syntax through the Postgres parser? Currently, all the
types that use typmod have to have special-purpose syntax to set it.
I'm not eager to see extension datatypes trying to do the same thing...
