The earlier errors are indeed fixed; now, I've been trying with the attached test case but I'm unable to find a query that improves with minmax index use. (it gets used sometimes but speedup is negligable). That probably means I'm doing something wrong; could you (or anyone) give some hints about use-case would be expected? (Or is it just the unfinished selectivity function?) Thanks, Erikjan Rijkers
