Hi Rahul,
Thanks for testing v3 on all four branches.
You are right about 17 and 18. I will change that sentence to
heap_xlog_visible() in those two versions, and add
"Backpatch-through: 17" to 0002. Both are commit message changes
only, so I will fold them into the next version and not post a v4
just for that.
I added a CommitFest entry so this is tracked for the November
releases.

Thanks,
Shihao
