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. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
