> Attached is an implantation of jsonb_delete that instead of taking a single key to remove accepts an array of keys
Since I already saw this patch, here is my small review.
Speaking about implementation of `jsonb_delete_array` - it's fine, but I would like to suggest two modifications:
* create a separate helper function for jsonb delete operation, to use it in both `jsonb_delete` and `jsonb_delete_array`. It will help to concentrate related logic in one place.
* use variadic arguments for `jsonb_delete_array`. For rare cases, when someone decides to use this function directly instead of corresponding operator. It will be more consistent with `jsonb_delete` from my point of view, because it's transition from `jsonb_delete(data, 'key')` to `jsonb_delete(data, 'key1', 'key2')` is more smooth, than to `jsonb_delete(data, '{key1, key2}')`.
I've attached a patch with these modifications. What do you think?
