Really?

regression=# create user joe;
CREATE ROLE
regression=# \c - joe
You are now connected to database "regression" as user "joe".
regression=> set log_statement = none;
ERROR: permission denied to set parameter "log_statement"

It is true that superusers can change that variable. However, if
you are trying to force monitoring of an uncooperative superuser,
you are in for a hard slog.
