Drat --- looks like the local buffer manager code has gotten out of sync
with the relcache code.  In particular I note the following in localbuf.c

        Relation    bufrel = RelationNodeCacheGetRelation(bufHdr->tag.rnode);

        /*
         * The relcache is not supposed to throw away temp rels, so this
         * should always succeed.
         */
        Assert(bufrel != NULL);

which was true at the time it was written, but is so no longer :-(

Will fix.
