Output clause for Upsert aka INSERT...ON CONFLICT

Unlike the MS SQL MERGE command's OUTPUT clause that gives the $action [INSERT / UPDATE  /DELETE] that was done during the upsert, the RETURNING clause of the pgsql does not return the action done. 

We need this so that the application can use that for auditing and UI purposes.

Is there any workaround to get this info ?

Or is there a way this enhancement can be requested in future PG versions ?

thanks,

Anand.
