While rebasing a patch broken by 4daa140a2f5, I noticed that the patch
does this:
@@ -63,6 +63,7 @@ enum ReorderBufferChangeType
REORDER_BUFFER_CHANGE_INTERNAL_TUPLECID,
REORDER_BUFFER_CHANGE_INTERNAL_SPEC_INSERT,
REORDER_BUFFER_CHANGE_INTERNAL_SPEC_CONFIRM,
+ REORDER_BUFFER_CHANGE_INTERNAL_SPEC_ABORT,
REORDER_BUFFER_CHANGE_TRUNCATE
};
I understand adding the ABORT right after CONFIRM
Isn't that an undesirable ABI break for extensions? It changes the value
for the TRUNCATE item, so if an extension references to that somehow
it'd suddenly start failing (until it gets rebuilt). And the failures
would be pretty confusing and seemingly contradicting the code.
FWIW I don't know how likely it is for an extension to depend on the
TRUNCATE value (it'd be far worse for INSERT/UPDATE/DELETE), but seems
moving the new element at the end would solve this.
