Hmm. Not tremendously helpful --- if you were to install the
appropriate postgresql-debuginfo RPM, the stack trace might get
more useful. However, this does appear to confirm the theory
that postmaster.c is doing proc_exit(1), and I don't see any code
paths in there where there isn't a error message logged first.
So right now I'm wondering whether you're not failing to notice
a relevant log message(s). You've evidently managed to launch
the syslogger --- where is it configured to write the postmaster
log?
