GIN support for @@ and @? jsonpath operators
This commit makes existing GIN operator classes jsonb_ops and json_path_ops support "jsonb @@ jsonpath" and "jsonb @? jsonpath" operators. Basic idea is to extract statements of following form out of jsonpath. key1.key2. ... .keyN = const The rest of jsonpath is rechecked from heap. Catversion is bumped.
