We have heard many times from people who don't have enough insight, or
enough debug support client-side, to know exactly what queries their apps are issuing. Disabling query logging would be a horrible setback for debuggability of such apps. How many times have you said "consult the postmaster log to find out what's going on"?
Not logging statements that fail to parse isn't the same as disabling query logging. If a statement fails to parse it can't really be considered a query in my opinion. When it fails to parse it *should* send a loud-and-clear error to whatever client-side application sent it. Granted a lazy developer could code their app to swallow all errors, but then I'd say they deserve the headache.
