Hi!
 
Database idd owner is role idd_owner
Database has 2 data schemas: public and firma1.
User may have directly or indirectly assigned rights in this database and objects.
User is not owner of any object. It has only rights assigned to objects.
 
How to drop such  user ?
 
I tried
 
    revoke all on all tables in schema public,firma1 from "vantaa" cascade;
    revoke all on all sequences in schema public,firma1 from "vantaa" cascade;
    revoke all on database idd from "vantaa" cascade;
    revoke all on all functions in schema public,firma1 from "vantaa" cascade;
    revoke all on schema public,firma1 from "vantaa" cascade;
    revoke idd_owner from "vantaa" cascade;
    ALTER DEFAULT PRIVILEGES IN SCHEMA public,firma1 revoke all ON TABLES from "vantaa";
    DROP ROLE if exists "vantaa"
 
but got error
   
    role "vantaa" cannot be dropped because some objects depend on it
    DETAIL:  privileges for schema public
 
in statement
 
    DROP ROLE if exists "vantaa"
 
How to fix this so that user can dropped ?
 
How to create sql or plpgsql method which takes user name as parameter and drops this user in all cases without dropping data ?
Or maybe there is some command or simpler commands in postgres ?
 
 
Using Postgres 9.1+
