I had to re-add the object name to the CheckSetNamespace prototype to
handle this particular check:

	/* check for duplicate name (more friendly than unique-index failure) */
	if (SearchSysCacheExists2(TYPENAMENSP,
							  CStringGetDatum(name),
							  ObjectIdGetDatum(nspOid)))

If you know how to get some struct attribute given a char * holding its
name, in C, I would adapt the patch and work on the refactoring asked
for by Tom.

Apart from that, it was just about adapting the call sites, which is
done in the attached set_schema.5.patch. Thanks!

Also attached, please find the complete version of ALTER EXTENSION ext
SET SCHEMA name; with support for all contrib extensions. That's the
example that allows to see the API (AlterFooNamespace_oid and _internal
functions) in action: that should help devising the best refactoring.
