It is a network error. The TCP/IP socket died somehow, and the FATAL
error logged. PostgreSQL then fell back to using the restore_command
defined in your recovery.conf file, but the WAL file had not yet been
shipped and the output logged. I imagine streaming replication happily
reconnected soon after. This is all quite normal.
