PostgreSQL Table inheritance in Rails?

Does anyone know how I can use PostgreSQL inheritance (see below) in a Rails migration? I don't mean single table inheritance supported in Rails with the 'type' attribute

Thanks, Chirag

CREATE TABLE cities (     name text,     population float,     altitude int -- in feet );

CREATE TABLE capitals (     state char(2) ) INHERITS (cities);

In this case, the capitals table inherits all the columns of its parent table, cities. State capitals also have an extra column, state, that shows their state.
