Hi!
jsonb operators ->text, ->>text,->int, ->>int use inefficient methods to access
to needed field, proportional O(N/2). Attached patch suggests for text operators
O(log(N)) and for integer - O(1). The fuctions with fast access already are
existed in current code and are used in contains operation, for example.
Attached patch uses that functions instead of sequentual loop over object/array.
