Table Inheritence...Just Columns?

Does a child table just inherit the columns from a parent table, or
are other table objects like column constraints and triggers
inherited?

Thanks,

From PostgreSQL 8.1 documentation (http://www.postgresql.org/docs/8.1/static/ddl-inherit.html)

"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"

Thanks,
