I've just started reviewing this patch. One comment I have for now is: this is categorized into Bug Fixes, but we have a workaround at least to the regression test case in the patch (ie, just reorder join clauses), so this seems to me more like an improvement than a bug fix. Sorry for the delay. Best regards, Etsuro Fujita
