Executing DML ends up executing code. Think predicated/expression indexes, triggers, default expressions etc. If a badly written trigger etc can be tricked to do arbitrary code exec, an attack will be able to run with the privs of the run-as user. How bad that is is influenced to some degree by the amount of privileges that user has. Greetings, Andres Freund
