DROP GROUP -- remove a user group
DROP GROUP removes the specified
group. The users in the group are not removed.
The name of an existing group.
It is unwise to drop a group that has any granted permissions
on objects. Currently, this is not enforced, but it is likely
that future versions of PostgreSQL will check for the error.
To drop a group:
DROP GROUP staff;
There is no DROP GROUP statement in
the SQL standard.
