pg_dump isn't coring, it's the backend.  Backend core files normally
appear in $PGDATA/base/whicheverdb/.  If you don't see one there,
it's likely because you started the postmaster under "ulimit -c 0"
(this seems to be the default for init-script-started processes on
at least some Linux distros :-().  Restart it with "ulimit -c unlimited"
and try again.
