As I said in another thread, I pushed parts 0002,0003,0004. Tomas said
he would try to rebase patches 0001,0005,0006 on top of what was
committed. My intention is to give that one a look as soon as it is
available. So we will have n-distinct and functional dependencies in
PG10. It sounds unlikely that we will get MCVs and histograms in, since
they're each a lot of code.
I suppose we need 0011 too (psql tab completion), but that can wait.
