Was this node the primary?

To me the below looks like there are replication slots set up that are
failing. Not sure how to deal with this at the moment. You might try
single-user mode:

https://www.postgresql.org/docs/10/app-postgres.html
Single-User Mode
...

and see if that at least gets the server started. This is a highly
restricted so do not expect much usability.

These servers did crash before however didn't' notice anything particularly wrong at the time. Perhaps a better check was in order.

Here is the result from attempting to start the DB in single user mode.
