What would be the point of reading it when the modules aren't 
initialized until after configuration has been parsed?

Naturally not. Log entries shouldn't, per common database practice, be 
normalised.

But why would anyone want nagios to read its configuration from a 
database? That would take a lot of effort and would cause a major loss 
of its present functionality, not to mention independence. If I heard 
voices about storing the runtime cache in database I could understand 
it, since it would then serve a purpose. I've written routines for that 
in PHP in case anybody's interested. It only works with nagios 2 though.
