BTW, Have you tried the patch suggested in the thread below? https://www.postgresql.org/message-id/20180629.173418.190173462.horiguchi.kyotaro%40lab.ntt.co.jp The above is a suggestion to manage statistics on shared memory rather than in a file, but I think this feature may mitigate your problem. I think that feature has yet another performance challenge, but it might be worth a try. The above patch will also require a great deal of effort to get into the PostgreSQL-core, but I'm curious to see how well it works for this problem.
