Problem with postgres restart: FileNotFoundError

[zvolsky]

There is FileNotFoundError in the pghoard log. When I restart postgres: pg_ctlcluster 9.5 main restart, then the immediate event has no problem, but the next one (I think it is at the archive_timeout end) will fail with FileNotFoundError.
