Hi Ramsey,

I used to handle unique constraint violations via a custom editing context 
delegate in editingContextDidFailSaveChanges().  This worked fine, but since 
upgrading to a more recent Wonder, this no longer works (that method is never 
called on the delegate), and now I get a stack trace containing an 
ERXValidationException.  I assume this is related to your commit here:

    Add unique constraint handling to ERXSQLHelper for postgresql.

(Until recently, the application in question was using Wonder dated prior to 7 
June, so the timing fits, at least.)  Could you explain how this new approach 
is supposed to work?  I'm sure it's better than what I was doing, but at the 
moment it breaks my delegate approach, and it's not clear whether I need to 
change every application that depended on that, or whether there's another 
centralised approach I could use.
