Yeah, I was coming to similar conclusions in the reply I just sent: we don't really want a policy that we can't put injection-point-based delays inside critical sections. So that infrastructure is leaving something to be desired. Having said that, the test script is also doing something we tell people not to do, namely SIGKILL the postmaster. Could we use SIGQUIT (immediate shutdown) instead? regards, tom lane
