Hi,
one more question: how can I set up vaccum handling in postgres to make it
less agressive? I'm faceing a problem where a batch process (inserting 184
records at once which takes 1 second in normal cases) stops because of a
dead lock. This occures (seemingly) only when a vacuum analyze is running.
Stopping vacuum calls, the problem thisappeares.
I set the vacuum_cost_delay option higher, but it doesn't help. I thought
that the more higher delay between vacuum portions the more time to finish
the inserts. Other settings have the default values.
To tell the truth I do not really understand this "cost" thing. Should I
treat it as a percent-like value?
My vacuum settings:
vacuum_cost_delay = 30
#vacuum_cost_page_hit = 1 # 0-10000 credits
#vacuum_cost_page_miss = 10 # 0-10000 credits
#vacuum_cost_page_dirty = 20 # 0-10000 credits
#vacuum_cost_limit = 200 # 0-10000 credits
