I think the operator (jsonb - jsonb) is logical because we have a shallow
concatenation function (something like a "union" operation), but we have
nothing like "set difference" and "intersection" functio

Hi all,
I was just looking through the new jsonb operators in the 9.5 release, and was
wondering if there's any future intention to add a delete operator that removes
element/pair matches? I.e. some sort of top-level "jsonb - jsonb" operator,
e.g.
# select '{"a":1, "b":2}'::jsonb - '{"b":2,
