We're going to need more details on what happened. What information is 
there in the server log around the crash? Did you get a core dump? Can 
you get a backtrace out of the core dump? 
(https://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Linux/BSD). 
Was this a one-off thing, or does it happen regularly? Can you reproduce it?

The latest minor version of the 9.6 series is 9.6.9, so you are a few 
versions behind. I don't know if it would help with this particular 
issue, but you should upgrade.
