I think that the compiler has caught an actual mistake here.
It looks to me like the patch is attempting to use a 'negative'
Oid to signal a problem, and that simply is going to break as soon
as the Oid counter runs past 2G. Perhaps InvalidOid is the thing
to use here? I did not look at the call sites though.
