If you look in the postmaster log file, you should find additional info
about the crash. 6.5.* libpq has a bug that makes it discard the last
backend error message if it sees an unexpected channel closure :-(.
So there is probably at least one error message that you're not seeing
on the client side --- but it should be there in the log file.
