I've attached an updated patchset against Amit's v49 faster partition
pruning patch [1].

v49 should also be patched with [2] and [3].

I'm pretty happy with patches 0001 to 0004. At the moment I'm still a
bit unsure of 0005. I need to do a bit more sanity checking on it,
mostly around the changes in planner.c. Although I am keen to see 0005
make it into PG11 as it does make running larger numbers of partition
more usable for UPDATE/DELETE too. Amit's improvements are really good
alone, but unfortunately, anyone who's waiting on us speeding up the
partition pruning in SELECT queries is probably also waiting on us
doing the same for UPDATE/DELETE. So I do think 0005 is important for
PG11, providing it's correct, of course.
