I took a quick look at these.  The v11 patch seems OK as far as it goes,
but I wonder if you shouldn't also include the RelationMapUpdateMap
hunk from the master patch, ie adding rejection of map changes in parallel
mode.

I don't have any objection to the master patch, but it'd be good to get
a +1 from someone who's spent more time with the parallelism
infrastructure than I have.
