Hi, I'm faced with a situation where I have
- a 1:n-relationship between Document and DocumentRevision-objects - want to delegate most properties of Document to DocumentRevison, which means I need an "active" revision. Modelling that active_revision as "normal" ManyToOne-relationship on the document gets me (understandably) into circular-dependency-hell. Now I know that you can create deferred constraints in some databases as "deferrable" which means you can create circular dependencies that must only be valid at commit-time, not while inserting. See e.g. http://www.network-theory.co.uk/docs/postgresql/vol1/CREATETABLE.html for PG doing this. Is there any way to exploit this kind of foreign key reference via elixir, or maybe SA itself?
