 | json_extract_path_text(text json, text path…) | text         | Extracts a JSON sub-object as text, defined by the path. Its behavior is equivalent to the [Postgres function with the same name][3]. For example, `json_extract_path_text(col, ‘forest')` returns the value of the key `forest` for each JSON object in `col`. See the example below for a JSON array syntax. |
 | json_extract_path(text json, text path…)      | JSON         | Same functionality as `json_extract_path_text`, but returns a column of JSON type instead of text type.                                                                                                                                                                                                        |
