I have created a group in postgres by inserting a group name into pg_group as suggested in the on-line documentation. I then add a user to this group using the appropriate create user syntax. Finally, I grant privileges to the group for a specific table. The system responds affirmatively up this point. When I then try to access this table as a user named in the group I get id errors. Grants seem to work nicely for individual users , but not for groups. Anyone else had this problem? Am I doing something wrong? Is this a bug? Any help would be appreciated? Thanks, Brad Rogers
