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?)
