Hi All, This patch is an add-on patch the version 15 posted earlier and should be applied on top of version 15. The following review items has been fixed:
- Fix the pruning code to prune all tuples upto and including the latest DEAD tuple in the chain. - Removed the heap tuple freezing changes because they are no longer required because of changes to the pruning code - Removed the HeapTupleSatisfiesAbort() code. We now collect all DEAD heap-only tuples while scanning the page. A separate bitmap is used to avoid duplicate entries in the deadtups array. This is required because a DEAD HOT tuple may be scanned twice, once while traversing the chain and then directly. - A little improvement to the WAL logging in heap_page_prune_defrag(). Earlier we were logging two WAL records, now we do that only once - The autoanalyze code now treats redirect dead line pointers as dead rows.
