You inherit the data as well, for example:

Parent Table:
[ 'column', ],
[ 1, ],
[ 2, ],

Child Table:
[ 'column', ],
[ 3, ],
[ 4, ],

select * from parent_table;
[ 'column', ],
[ 1, ],
[ 2, ],
[ 3, ],
[ 4, ],

For a more concrete example:

create table parent (
col integer
);

create table child () inherits (parent);

insert into parent values (1);
insert into parent values (2);
insert into child values (1);
insert into child values (2);
insert into child values (3);
insert into child values (4);

select 'Selecting from parent';
select * from parent;

select 'Selecting from child';
select * from child;

Best of luck!
