I was wrong. GIN check does similar gin_refind_parent() to lock pages in bottom-up manner and truly verify downlink-child_page invariant. Here's v17. The only difference is that I added progress reporting to GiST verification. I still did not implement heapallindexed for GIN. Existence of pending lists makes this just too difficult for a weekend coding project :( Thank you! Best regards, Andrey Borodin.
