  tables.
  
  Primary and foreign keys are informational only and are not enforced. Foreign
  keys must reference a primary key in another table. This primary key is the
  parent constraint of the foreign key and the table this primary key is on is
  the parent table of the foreign key. Similarly, the foreign key is the child
  constraint of its referenced primary key; the table of the foreign key is the
  child table of the primary key.
  
  You can declare primary keys and foreign keys as part of the table
  specification during table creation. You can also add or drop constraints on
  existing tables.`,
