Hi Guys. I got one problem. I need to give some of the non-super users( kind of dba) to get the privileges to can cancel other users's query, DML. After I granted the execute on pg_cancel_backend and pg_terminate_backend function to them, they still get the error message as follows when they call these two function : ERROR : must be superuser to signal other server processes. QUestion : is it possible to make the non superuser to have these two privileges?? Thanks. Regards.
