I think this code has a bigger problem: it should not be using
RelationIdGetRelation and RelationClose directly. 99.44% of
the backend goes through relation_open or one of the other
relation.c wrappers, so why doesn't this?
Possibly the answer is "it copied the equally misguided code
in pgoutput.c". A quick grep shows nothing else doing it this
way.
