I checked this patch.
It seems to me it replaces whole of get_role_oid() in has_*_privilege
functions by the new get_role_oid_or_public(), so this patch allows
to accept the pseudo "public" user in consistent way.
The pg_has_role_*() functions are exception. It will raise an error
with error message of "role "public" does not exist".
Is it an expected bahavior, isn't it?

It seems to me fair enough, but I'm not a native in English.

Tom Lane suggested to add missing_ok argument, although it is not a must-
