This is not a "server does not start" problem. This is something sending SIGINT to the postmaster, which makes it terminate. Do all the log files mention "incomplete startup packet" right before the shutdown request? That's not a very usual message, and it might be a clue to what's causing the SIGINT. You might try setting log_line_prefix to '%m ' in postgresql.conf to add timestamps to the log messages --- that would tell us more about which messages are actually appearing close together in time. regards, tom lane
