What exactly do you mean by "killing the postmaster"? If you > mean SIGKILL or something, one problem with 11 is that
I mean unqualified /bin/kill which is kill -TERM (-15 in linux). I gather (pun acknowledged but not intended) you mean "one problem with PG v11" and not "one problem with kill -11" (which is what I first thought, although I was somehow confusing kill -9, and since I don't know why anyone would ever want to manually send SIGSEGV). I think you're suggesting that's a known issue with v11, so nothing to do. Thanks, Justin
