That doesn't tell me anything.  The functionality of the ACL system is 
to answer questions like "does user X have privilege Y on object Z".  
It seems that this question can be answered using existing facilities.  
Additionally we have information schema views that list existing 
privileges, and those views are defined using existing facilities.  It 
appears that your tables mostly duplicate that.  Can you say in words 
what information you are missing?
