I decided it would be a shame for this to miss v13, seeing that
(a) it'd provide real-world use of that ALTER TYPE code, and
(b) we already bumped ltree's extension version for v13.
So I went ahead and rebased this, reviewed and pushed it. The
main non-cosmetic thing I changed, other than using ALTER TYPE,
was that you had the output functions looking like this:
pq_sendtext(&buf, res, pg_mbstrlen(res));
That's just wrong; it should be plain strlen(). Did you copy
that coding from someplace? I could not find any similar
occurrences in our code tree.
