title: how do I find what privileges a group has in redshift?
body: <p>I'm having a peculiar problem with one group.
  I have revoked all database access for this group
  I have revoked all schema access for this group
  I have revoked all table access for this group
  I have revoked all execute privileges on functions
  When I try to drop the group, I get an error saying it cannot be dropped because the group have a privilege on some object.</p>
  
  <p>How can I find out what privileges a group has on redshift?
  Thanks</p>
