One of the idea's that came up through the discussion was to make the
rewriter responsible for collecting check constraints such as the local
check condition. They would be pushed down to the executor then where the
correct constraints would be applied. However, i'm currently not in the
position to say if this is doable right now.

The original updatable views patch tracked the state of required and
applied rule conditions during rewrite. This way it applied only the rule
conditions of the specified view in cascading updates.
