Later in the dump file you should see something like this:
ALTER TABLE ONLY cases
ADD CONSTRAINT cases_pkey PRIMARY KEY (id);
Presumably that's because adding the primary key constraint after
populating the table is more efficient than populating the table
with the constraint (and the associated index) in place.
