I think it is a good question for the hackers list.

Last time I used groups successfully I had to create the group as
a unix group, then insert the unix group id into the grosysid column.
Actually any id that shows in /etc/groups is ok, (but imho a bug).
I think it is also a requirement, that the group id is not used as a
user id in pg_shadow.
I am not sure that anyone knows the initially intended architecture.
Please speak up anybody, if you know the intended/wanted design.
