Bug / shortcoming in has_*_privilege

test_us@workbook=# select has_table_privilege( 'public', 'test', 'SELECT' );
ERROR:  role "public" does not exist
test_us@workbook=# 

So there's no way to see if a particular privilege has been granted to public. ISTM 'public' should be accepted, since you can't use it as a role name anyway...

test_us@workbook=# create role public;
ERROR:  role name "public" is reserved
test_us@workbook=# create role "public";
ERROR:  role name "public" is reserved
