I really dislike the API you've chosen for upper_str/lower_str ---
overwriting the input on the assumption that it's long enough is a
buffer overrun bug waiting to happen, because (at least in utf8)
changing case doesn't preserve the byte length of the string.
Please make them return a freshly palloc'd string instead.
