How to specify an index on Bag in Nhibernate?
===

I have NHibernate set up with Postgre database. I'm using mapping by code in combination with ConventionModelMapper.

NHibernate by default does not create indexes for foreign keys. For a simple column I can set foreign key using `Index` method in my `Property` mapping. However there is no such methodfor `Bag` mapping.

Will I have to define Inverse relationships to define indexes?
