Something is creating transactions in a read-only mode, though it's  
not clear why that would change from 7.4 to 8.0 (or were you using  
something even older?) I suspect it's an abstraction layer trying to  
be cute and getting things wrong, but that's just a guess. Turning on  
query logging should provide insight.
