Ok.  What am I missing here?  B_USER is a defined Group Role

CREATE ROLE "B_USER"
  NOSUPERUSER NOINHERIT NOCREATEDB NOCREATEROLE;


GRANT SELECT PRIVILEGES

TO ROLE B_USER;

Nets this ---------------------------------------

ERROR:  syntax error at or near "B_USER"
LINE 3: TO ROLE B_USER;
                ^
