Hi,
I am looking at a postgres 9.6 on rh7
I see that checkpoint_write_time is huge which looks quite strange as the average amount of data written is not that big.
For example in 5:30 hours today, data from pg_stat_bgwriter view, comparing values at 11AM and 4h30PM :
checkpoint_write_time 6986324
buffers_checkpoint 182447
so, to my understanding, it takes almost 2 hours to write 1.6 GB of data.
Can someone either correct my understanding, or shed some light on what can cause this ??
thanks,
