Or even:

iptables -I INPUT -p tcp --dport 5432 -j DROP

Keep in mind that both of those are simulating network failures, not
a "server crash". But network failures are something your application
should handle gracefully too. :) To make something look like a real
crash, you should do a real crash. In this case, kill -9 the backend(s).

A server crash is a pretty rare event in the Postgres world, so I
would not spend too many cycles on this...
