Two issues that I saw: The first syncfs message is not output, because it's before InitStartupProgress() is called:
2021-08-03 07:53:02.176 CDT startup[9717] LOG: database system was interrupted; last known up at 2021-08-03 07:52:15 CDT 2021-08-03 07:53:02.733 CDT startup[9717] LOG: data directory sync (syncfs) complete after 0.55 s 2021-08-03 07:53:02.734 CDT startup[9717] LOG: database system was not properly shut down; automatic recovery in progress FP exception when the GUC is set to 0: 2021-08-03 07:53:02.877 CDT postmaster[9715] LOG: startup process (PID 9717) was terminated by signal 8: Floating point exception Probably due to mod zero operation. This prevents the process from starting. + enable_timeout_after(LOG_STARTUP_PROGRESS_TIMEOUT, + (interval_in_ms - (elapsed_ms % interval_in_ms))); -- Justin
