I've tried searching the documentation to answer this question but could 
not find anything. When trying to choose the optimal fillfactor for an 
index, what is important the number of times the row is updated or the 
column indexed upon is updated? In my case each row is updated on 
average about 5 times but for some of the columns with indexes don't 
change after insertion ever. thanks for any advice

It's the number of times the row is updated, regardless of which columns 
are changed.
