OK, in that case we're going to need you to extract a self-contained
test case for us to poke at.
If you don't want to do that, you could look into the postmaster log
to see if it offers any more hints about what happened, or you could
see if there's a core file to try to extract a stack trace from.
But we can't really promise that we can figure it out without a
test case.
