How do I print a message in a function?

I did something like

create function test() returns integer as
'
declare   msg varchar;
begin   msg := "test";   RAISE NOTICE "message is " || msg;
end'
language 'plpgsql';

The function compiled without any error, however, when I tried to run it
as select test(); it broke down with an error message " Unterminated " "

Can anyone help me on this?

Thanks!
