There sure oughta be a corefile after a SIGSEGV.  Hmm.  How are you
starting the postmaster --- is it from a system startup script?
It might work better to start it from an ordinary user process.
I discovered the other day on a Linux box that the system just plain
would not dump a core file from a process started by root, even though
the process definitely had nonzero "ulimit -c" and had set its euid
to a nonprivileged userid.  But start the same process by hand from an
unprivileged login, and it would dump a core file.  Weird.  Dunno if
your platform behaves the same way, but it's worth trying.
