That does not look like PostgreSQL crashed but is being shutdown by RDS services due to a DOS attack.
Two things;
1. A firewall should be blocking the incoming rouge traffic to protect the given server; otherwise the system is open to a DOS attack.
2. Why is PostgreSQL accessible on the internet? Normally DB servers are at least 3 deep from the internet and only internal trusted nodes should be connecting to the database.
