SQLAlchemy declarative: defining triggers and indexes (Postgres 9)

Question

Is there a way in the SQLAlchemy class of a table to define/create triggers and indexes for that table?

For instance if i had a basic table like ...

class Customer(DeclarativeBase):
    __tablename__ = 'customers'
    customer_id = Column(Integer, primary_key=True,autoincrement=True)
    customer_code = Column(Unicode(15),unique=True)
    customer_name = Column(Unicode(100))
    search_vector = Column(tsvector) ## *Not sure how do this yet either in sqlalchemy*.

I now want to create a trigger to update "search_vector"

CREATE TRIGGER customers_search_vector_update BEFORE INSERT OR UPDATE
ON customers
FOR EACH ROW EXECUTE PROCEDURE
tsvector_update_trigger(search_vector,'pg_catalog.english',customer_code,customer_name);

Then I wanted to add that field also as an index ...

create index customers_search_vector_indx ON customers USING gin(search_vector);

Right now after i do any kind of database regeneration from my app i have to do the add column for the tsvector column, the trigger definition, and then the index statement from psql. Not the end of the world but its easy to forget a step. I am all about automation so if I can get this all to happen during the apps setup then bonus!
