为什么bgwriter不运行

[zeeeitch]

select name,setting from pg_settings where name like 'bg%'

"bgwriter_delay";"200"
"bgwriter_lru_maxpages";"100"
"bgwriter_lru_multiplier";"10"


select buffers_clean,buffers_checkpoint,buffers_backend,
(checkPoint_write_time+checkpoint_sync_time)/1000||'s' as "checkPoint_time",
(checkPoints_timed+checkPoints_req) as "checkPoint runs",
buffers_alloc from pg_stat_bgwriter

0;89;1;"0.1s";1;1

buffers_clean 永远是0 ，为什么？

没看出你这个bgwriter进程不运行。

改了sharedbuffer，改小了，buffers_clean过一段时间就有数值了

[zeeeitch]

buffers_clean为0，就是bgwriter不运行吧？
