And this is the behaviour I was expecting by quote_ident and format('%I'), so I still don't see the case for the bug here. Unless you are mixing upper and lower cases passing arguments to the function, such as clone_schema( 'foo') and expecting it will clone "FOO". That's my fault, I cannot see the problem with quote_ident as it has been applied consistently. Luca
