Hi,
Is there a way to know which rows were INSERTed and UPDATEd when doing a INSERT ... ON CONFLICT UPDATE? Probably via pseudo column indicating INSERT / UPDATE ?
The RETURNING clause just allows us to return columns, but am unable to find a way to know 'what' happened to a given row.
Any pointers would be helpful.
Couldn't find anything related in 9.5devel docs either.
