Oh, I didn't remember there were some for normal vacuum, just the 
auto_vaccuum.

vacuum_cost_delay = 250
vacuum_cost_page_hit = 1
vacuum_cost_page_miss = 10
vacuum_cost_page_dirty = 20
vacuum_cost_limit = 1000

Are those values to high/low? What should one use?

I think I will disable it at this one server, setting
vacuum_cost_delay = 0
because it's only one DB here. Still, I'd like to understand what values 
would be reasonable on a server with many DBs, as we have some.
