You're evidently tripping over some kind of bug, but we can't help you
without a lot more detail than this.  Try to identify the exact command
that's crashing (hint: turn on log_statements and watch the postmaster
log).  See if you can put together a self-contained script that causes
the crash.  That will let us fix the problem, and it might let you find
a workaround to reload your data even in advance of a real fix.
