But how would we know that a particular address range is more unlikely than others to have a conflict? (And even if we do know that, what happens when there is a conflict anyway?) I sure don't want to be in the business of figuring out what to use across all the different Windows versions there are, to say nothing of the different antivirus products that might be causing the problem. Also, the big picture here is that we ought to be working towards allowing our Windows builds to use ASLR; our inability to support that is not something to be proud of in 2017. No predetermined-address scheme is likely to be helpful for that. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
