Can you share what the aggressive BGW settings you settled on were? 
Knowing that information would allow giving better suggestions on how to 
translate what you're currently doing into the very different settings 8.3 
uses in this area.  Also be helpful to know about how often you have a 
checkpoint with your current configuration, and how big your 
shared_buffers is to get a general context for the size/frequency of 
potential checkpoint problems.
