Cool. I was just reacting to the fact that you highlighted merge joins in parallel queries with a partial plan on the outer side only, which was a new feature back in 2017 when 10 came out (and was already supported for hash joins and nested loops since 9.6), without mentioning that in 2018 when 11 came out we got parallel hash joins that can use a partial plan on both sides of the join.
