I don't know of any public/open code, but I have seen DefineIndex()
being used directly in some company's private code. And it's probably
not a good idea to do so.

Since such code should also adapt to be safe, it's probably a good idea
if it breaks. If such code is used without recompiling against an
updated PG, it's likely that it will error out with a somewhat strange
message (Cache lookup failure for Oid <ptr as uint32>), but it shouldn't
crash.
