Today the database shut down unexpectedly. I have included the log file that shows the shutdown. Can anybody tell me why this happened and how I can make sure it doesn't happen again.
The only thing I can think of that I did was to specify a password for the postgres user in the operating system.
Here is the log file. Very strange.
