How to make ARRAY field with foreign key constraint in SQLAlchemy?

问题

How to make column with ARRAY(Integer) type, where each integer is primary key from some other table? If it's impossible, how to achieve similar table relationships with other method?

As of PostgreSQL 9.3, this is not implemented, see http://blog.2ndquadrant.com/postgresql-9-3-development-array-element-foreign-keys/ One should turn array into other table.
