I am always confused by this implementation detail. restore_command fails? Fine, let's just read file from pg_wal. But
thisis different topic...
I do not know the history of this fatal ereport. It looks like "must specify restore_command when standby mode is not
enabled"check is only intended to protect the user from misconfiguration and the rest code will treat empty
restore_commandcorrectly, just like /bin/false. Did not notice anything around StandbyMode conditions.
