A backend SEGV crash like this would normally leave a core file in the
$PGDATA/base/whicheverdb/ directory. If you don't see one, the odds are
that the postmaster and hence the backend was launched with a ulimit
setting that prohibits dumping core ("ulimit -c 0", I think, but check
your local man pages). Unfortunately a lot of Linux distros are set up
in such a way that any process launched from a system startup script
runs with exactly that ulimit setting by default. You might try
tweaking your PG start script to do "ulimit -c unlimited" just before
starting the postmaster.
