RAISE NOTICE ... and CONTEXT field of the error report.

Hey all,

Is there way to turn off printing of CONTEXT field of the error report
in the following case:

create or replace function foo() returns void language plpgsql as $$
begin
raise notice 'notice from foo()';
end;
$$;
create or replace function bar() returns void language plpgsql as $$
begin
perform foo();
end;
$$;

wog=# select foo();
NOTICE: notice from foo()
foo
-----

(1 row)

wog=# select bar();
NOTICE: notice from foo()
CONTEXT: SQL statement "SELECT foo()"
PL/pgSQL function bar() line 3 at PERFORM
bar
-----

(1 row)

If it does not possible, I would like to have this feature. From the POV
of the PL/pgSQL user I think it should be customizable mode of PL/pgSQL.
