Comment:
I'm moderately surprised that Django does this -- firstly because I wasn't
aware it was valid SQL in the first place, but secondly because I don't
remember implementing anything like that when I committed the aggregation
codebase. It's entirely possible something has changed since I last looked
at the code, but it doesn't strike me as a very "Django" thing to find in
a codebase.
Can you give a specific example of a query (ideally one in Django's test
suite) that does this?
