Description:        Core dump while pgdump DB

I tried to export a large DB from PostgreSQL and a core_dump file was found
after the process.

The following was what I found from the core_dump:

We need to see the backtrace (gdb "bt" command) from this.  Also,
did you look in the postmaster log?  Signal 6 probably means that
an Assert() test failed, in which case something would have been
printed in the log before aborting.
