Note that we can only do this when the result type stays the same.
It does not for json_each/json_each_text or
json_extract_path/json_extract_path_text, which is why we have
different functions for those cases.
In C code, if I extract a value using json_object_field or
json_array_element, is there a way to turn it into the dequoted version,
that is, the value that I would have gotten had I called
json_object_field_text or json_array_element_text instead?

I wrote a quick and dirty hack in the event triggers patch that just
removes the outermost "" and turns any \" into ", but that's probably
incomplete.  Does jsonfuncs.c offer any way to do this?  That might be
useful for the crowd that cares about the detail being discussed in this

I'm not sure I understand the need. This is the difference between the _text variants and their parents. Why would you call json_object_field when you want the dequoted text?
