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).
