Hi,

Why is that you would expect poor performance for say 1000 or more? I 
have a ~1000 inherited tables and I don't see any significant slowdowns. 
I only ever access a single inherited table at a time though in this 
situation. I suppose I am using inheritance only for organization in 
this case...

Thanks,
Gerald
