We shouldn't set successor[whatever] to an offset number that is less than FirstOffsetNumber or more than maxoff. We already avoided that for redirects, but not for CTID links. Allowing bad offset numbers into the successor[] array causes core dumps. We shouldn't use HeapTupleHeaderIsHotUpdated() because it checks stuff other than the status of the infomask2 bit HEAP_HOT_UPDATED. We only care about the status of that bit, not the other stuff that HeapTupleHeaderIsHotUpdated() checks. This mistake can cause verify_heapam() to report corruption when none is present. The first hunk of this patch was written by me. The other two were written by Andres Freund. This could probably do with more review before commit, but I'd like to try to get the buildfarm green again sooner rather than later.
