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.​

thanks
