Every time or only sometimes?
i checked again, and it seems to be only sometimes.. and during these times there are lot of other queries too running which I can see from pg_stat_activity;
Upgrade to 8.3 will help as checkpoint writing algorithms were optimized there for lots of RAM.
I already am running 8.3.1 [ i mentioned in subject]. I am having the default settings for those. can you pl. share the settings for check points:
current settings all default #checkpoint_segments = 3 # in logfile segments, min 1, 16MB each #checkpoint_timeout = 5min # range 30s-1h #checkpoint_completion_target = 0.5 # checkpoint target duration, 0.0 - 1.0 #checkpoint_warning = 30s # 0 is off
this is what I have on pg_stat_bgwriter ; how much should I increase checkpoint_segment & checkpoint_completion_target to? thanks a lot!
