Patch looks fine to me. One minor quibble: in pruneheap.c you have

/*
- * Prune specified item pointer or a HOT chain originating at that item.
+ * Prune specified line pointer or a HOT chain originating at that item.
*
* If the item is an index-referenced tuple (i.e. not a heap-only tuple),

Should "that item" also be re-worded, for consistency?
