Yep. We have already beefed up group handling quite a bit in the past few releases, so if we can take it the extra steps needed, we can just make ROLE and GROUP synonymous and be done with it. I think the one missing item mentioned was for group ownership of an object. However, if we give group _permission_ to the object, I am not sure why ownership is an issue.

How about doing it > the other way: > ALTER USER blah COPY PERMISSIONS TO chriskl; That seems a bit bizarre to me. The user whose permissions are actually being altered by this command is chriskl, not blah, so ISTM chriskl is the name that should be specified as being ALTERed. In other words I like FROM, not TO. But: nearby, Peter E. complains that this is a poor substitute for implementing SQL-spec roles. He's got a point --- especially since roles could be made installation-wide, and thus they'd get around the problem that ALTER USER COPY couldn't realistically do anything about permissions in other databases. GRANT ROLE foo TO USER bar (or whatever the spec syntax is) would be an installation-wide change and so would indirectly grant any privileges the role has in other databases. While I haven't thought about it very hard, it seems to me that a role might be equivalent or nearly so to a group. If so, we might be able to support roles with little more than some syntactic-sugar work ... regards, tom lane ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

I > can't promise that I can implement it... In this scenario, 'blah' is the user who will eventually be dropped, and chriskl is taking over ownership of his 'stuff' right? How about doing it the other way: ALTER USER blah COPY PERMISSIONS TO chriskl; Hmm, in fact, I can imagine uses for both forms: creating a 'template' user who you COPY PERMISSIONS FROM when creating a new user of that type, who will then be customized, so you can't use GROUPs. Hmm, what about GROUP membership? Those get copied as well? Ross ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]

Often I need to remove a user and cede their permissions to someone else. How about something like this: DROP USER blah PERMISSIONS TO chriskl; or maybe GRANT ALL USER blah TO chriskl; ??? Chris ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster
