Do you mean these parameters have been removed starting 9.X?
As I see on
http://www.network-theory.co.uk/docs/postgresql/vol3/BackgroundWriter.html
,these parameters were added starting from 8.0 right?

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...
