PostgreSQL version 8.3.14
 
There appears to be no documentation on the following error code:
Error code is: 80S01
Message: "The backend has broken the connection. Possibly the action you have attempted has caused it to close."
 
I was expecting the code to be something like: |  | crash_shutdown, however that appears to be under a | 
 completely different error class: 57P02.
