Hi,
hstore have only key-value pairs, but in json can have same behavior -
only equal objects are removed:
SELECT '{"a": 1, "b": {"c": 2}}'::JSONB - '{"a": 1, "b": {"c": 3}}'::JSONB
'{"b": {"c": 2}}'
SELECT '{"a": 1, "b": {"c": 2}}'::JSONB - '{"a": 2, "b": {"c": 2}}'::JSONB
'{"a": 1}'
Hi,
some users and me used hstore - hstore for example storing only changed
rows in trigger like:
hsore(NEW) - hstore(OLD)
There isn't same operator/function in JSON/JSONB. We can only remove keys
from JSONB, but not equal key-value pairs. Is there any chance to have
same feature with
