PG::UnableToSend: server closed the connection unexpectedly

This is not a crash per se:

Caused by: PG::UnableToSend: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

The postgres DB going away is not something that we normally see.

How did you install? What is different/custom about your setup?
