Re: Add counted_by attribute

[Peter Eisentraut]

Ok, all the infrastructure is in place now.  I'm working through the 
attribute additions now.

One thing to think about is that adding these attributes to server 
header files would also affect extensions.  I think we might want to do 
some research about that.  Like, is the normal API to fill in the 
structure yourself, or are there wrapper functions that are mandatory to 
use?  I'm going to park that for the moment and work through the 
attribute additions in .c files first.
