Simon Riggs 2686ee1b7c Collect and use multi-column dependency stats ... Follow on patch in the multi-variate statistics patch series. CREATE STATISTICS s1 WITH (dependencies) ON (a, b) FROM t; ANALYZE; will collect dependency stats on (a, b) and then use the measured dependency in subsequent query planning. Commit 7b504eb282 added CREATE STATISTICS with n-distinct coefficients. These are now specified using the mutually exclusive option WITH (ndistinct).
