Thread: Public header files change

It seems to be unlikely to me, but are the changed symbols mentioned in
git-log commit message 5f173040e324 supposed to be used other than
internally?  Snip:
   Avoid repeated name lookups during table and index DDL.   ...   to the Constraint node (FkConstraint in 8.4).
Third-partycode   calling these functions or using the Constraint node will require   updating.   ....
 

These seem to be pretty internal symbols to me, but I rather asking here.
Is there some project we know off that is using this functions (or is
there some obvious usecase for third-parties)?

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.
