I've tried to take an attempt to review some patches of this patchset. It's huge and mostly polished.

In a step "Pass down information on table modification to scan node" you pass SO_HINT_REL_READ_ONLY flag in IndexNext()
andBitmapTableScanSetup(), but not in IndexNextWithReorder() and IndexOnlyNext(). Is there a reason why index scans
withordering cannot use on-access VM setting? 

Also, comment about visibilitymap_set() says "Callers that log VM changes separately should use visibilitymap_set()" as
ifvisibilitymap_set() is some other function.
