PostgreSQL is a object-orientated database. The main feature of a object-orientated database is that tables can inherit from other tables, which means they automatically get all the data columns of the table they inherit from (similar to object inheritance in object-orientated programming languages).

INHERIT variant of the
ALTER TABLE statement.
