The following bug has been logged online:

Bug reference:      2561

PostgreSQL version: 8.01
Operating system:   Documentation
Description:        Manual is wrong: You can't grant a group to public
Details:

The manual page for grant here:

http://www.postgresql.org/docs/8.1/interactive/sql-grant.html

indicates that you can grant a group to public.  The discussion of
priveleges here:

http://www.postgresql.org/docs/8.1/interactive/privileges.html

indicates that you can't, and experiment with 8.01 confirms that you can't
as well.  I'm assuming this is a cut and paste error with the documentation.
