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, "a":4}'::jsonb;
?column?
----------
{"a": 1}
(1 row)
Or would this behaviour be classed as incorrect in some way?
Thanks
