Hi,
I found a small error in "5.8 Inheritance" where it says:
Check constraints can be defined on tables within an inheritance
hierarchy. All check constraints on a parent table are automatically
inherited by all of its children. Other types of constraints are not
inherited, however.
However, "not null" constraints also will be inherited. Unique
constraints, primary key and foreign keys are not.
