PostgreSQL array types support

[Sly]

Hello. 

PostgreSQL has an awesome support of arrays of basic types. For now we are using it with IUserType implementation. But wouldn't it be nice if NHibernate could do it with custom PostgreSQL91Dialect. I could do a pool request for this, but need some directions in a way of implementation. 

Should this dialect register base types for all basic array types using RegisterColumnType as done in this example? Or if it is implemented inside NHibernate code it can be done in a better way? 

Thanks.

+1 I would really like to see NHibernate support PostgreSQL arrays too. I am also currently using an IUserType for arrays.
