Huh. What exactly do you mean by "killing the postmaster"? If you mean SIGKILL or something, one problem with 11 is that gather_readnext() doesn't respond to postmaster death. I fixed that (and every similar place) in master with commit cfdf4dc4fc9, like so: - WaitLatch(MyLatch, WL_LATCH_SET, 0, WAIT_EVENT_EXECUTE_GATHER); + (void) WaitLatch(MyLatch, WL_LATCH_SET | WL_EXIT_ON_PM_DEATH, 0, + WAIT_EVENT_EXECUTE_GATHER); -- Thomas Munro http://www.enterprisedb.com
