With unlogged tables I still see data written to the device every 10 seconds, so I did some digging and found bgwriter_delay = 10000, again with an artifical 10s limit applied on the parameter. To disable background writing, I set bgwriter_lru_maxpages = 0 which seems to help. What is left, is the wal-writer-process which still seems to fsync every 10s, even though there is no data written to any logged table.
