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
