Only if there's demand for it. Is there?
I'm certainly worried (paranoid?) about it. Postgres is very good
about not silently dropping data and this seems a glaring departure
from that. I haven't looked yet but I'm hoping this could at least be
added as an extension without duplicating a bunch of the existing JSON
stuff.
What on earth does this have to do with duplicate keys? The jsonb input
rules on duplicate keys are very clear, incidentally, and follow the
practice of most JSON processors (duplicates are discarded, last one
wins.) But that has nothing at all to do with this feature, really.
This feature can NOT be added as an extension, since it requires grammar
processing modification.
