Alvaro Herrera 919f6d746e Improve multivariate statistics documentation ... Extended statistics commit 7b504eb282 did not include appropriate documentation next to where we document regular planner statistics (I ripped what was submitted before commit and then forgot to put it back), and while later commit 2686ee1b7c added some material, it structurally depended on what I had ripped out, so the end result wasn't proper. Fix those problems by shuffling what was added by 2686ee1b7c and including some additional material, so that now chapter 14 "Performance Tips" now describes the types of multivariate statistics we currently have, and chapter 68 "How the Planner Uses Statistics" shows some examples. The new text should be more in line with previous material, in (hopefully) the appropriate depth. While at it, fix a small bug in pg_statistic_ext docs: one column was listed in the wrong spot.		2017-04-20 15:43:33 -03:00
