Wait a second. Which side is segfaulting here? I've been assuming that
you were talking about a backend segfault, but maybe I misunderstood
completely. If it's psql dumping core then we have quite a different
issue.

Probably. "ulimit -c 0" is a common default these days. Try "ulimit -c
unlimited" before starting the postmaster (resp. psql).
