[Dbix-class] Dynamic constraints on PostgreSQL arrays

[Kaare Rasmussen]

Hi 

I'm in the process of redesigning a database. Before I go too far, I'd like 
to know if it is possible to add constraints to a column in DBIx::Class. 
Something that is executed in D::C, not in the database. 

If so, does it work with the array type in PostgreSQL? 

The reason being that I'd like to maintain integrity _and_ be (somewhat) 
flexible at the same time. Somewhere in my system I'd note that col{1} 
references table a column a1 and that col{2} references table b column b1.
