These messages indicate that psql crashed, not the backend. Did you not
see any interesting messages on the client side? Can you get a stack
trace from the psql crash?

Also, as someone already mentioned, the current release in the 7.3
branch is 7.3.18 not 7.3.8. If you want us to expend time looking for
the problem, it would be polite to first make sure it's not a
long-since-solved problem.
