Hm.  When I've seen a backend crash without leaving a core file,
it's usually because the backend ran up against the system's
per-process memory limit.  (Many kernels seem to choose not to
drop a core file when they kill a process for memory exhaustion.)
You could check that theory by watching the process's memory usage
with "top".

Anything in the postmaster log?
