Either thats not true or you cargo culted loads of your config from a
significantly older pg version.

Things like:

#bgwriter_delay = 200 # 10-10000 milliseconds between rounds
bgwriter_lru_percent = 0 # 0-100% of LRU buffers scanned/round
#bgwriter_lru_maxpages = 5 # 0-1000 buffers max written/round
#bgwriter_all_percent = 0.333 # 0-100% of all buffers scanned/round
bgwriter_all_maxpages = 0 # 0-1000 buffers max written/round

make me very suspicious.

As I said, I would check the variables I referenced in my first post...
