I wonder if we even need to retain the bgwriter_percent GUC var. Is 
there actually a situation in which the combination of bgwriter_maxpages 
and bgwriter_delay does not give the DBA sufficient flexibility in 
tuning bgwriter behavior?

Is the plan to make bgwriter_percent = 100 the default setting?
