I was looking at this patch set, and 0005 has attracted my attention
here:

Since 16828d5, this variable is indeed unused. Now, the same commit
has removed the following code:
- if (found != ndef)
- elog(WARNING, "%d attrdef record(s) missing for rel %s",
- ndef - found, RelationGetRelationName(relation));

Should we actually keep this variable and have this sanity check in
place? It seems to me that it would be good to have that, so as we
can make sure that the number of default attributes cached matches
with the number of defaults actually found when scanning each
attribute. Adding in CC Andrew as the author of 16828d5 for more
input.
