There is no uniqueness in CouchDB and I think will never be.

PS: I think that will be cool to have a feature to declare such
constraints. And mark documents (if constraint void) just like them
marked when conflict occurs (doc._conflict). Something like
doc._constraints["unique_timestamp"]. Then it will be possible to
create a view and retrieve a list of documents with constraints
violation.
But isn't this possible to do just by writing a view with a suitable reduce function?
