From 315264d70128445fd53de199e16bb8aa562cf36f Mon Sep 17 00:00:00 2001 From: Noah Misch Date: Tue, 10 Dec 2024 13:51:59 -0800 Subject: Fix elog(FATAL) before PostmasterMain() or just after fork(). Since commit 97550c0711972a9856b5db751539bbaf2f88884c, these failed with "PANIC: proc_exit() called in child process" due to uninitialized or stale MyProcPid. That was reachable if close() failed in ClosePostmasterPorts() or setlocale(category, "C") failed, both unlikely. Back-patch to v13 (all supported versions).
