Hi List,
a workaround for my own problems as described below:
In the following system-table-colums (type aclitem[]) I replaced all entries with these non-existing Group-Roles with
somethinglike {postgres=arwdDxt/postgres,kniprath=arwdDxt/kniprath}, this resets the privileges to just these two
(Admin-)users.
pg_namespace.nspacl
pg_class.relacl
pg_default_acl.defaclacl
I dont't think it's good practice to update systemtables manually, but apparently I previously did something in
mydatabase, that messed the contents.

Betreff: strange problem with not existing roles
Hi list,
I have a strange problem in postgres (PostgreSQL 9.3.1, compiled by Visual C++ build 1600, 64-bit), there are granted
privilegeson schemas, tables, columns for roles that don't exist.
Example:
In pgAdmin for schema user_data the follwing wrong grants are reported:
...
GRANT ALL ON SCHEMA user_data TO "482499";
GRANT ALL ON SCHEMA user_data TO "17708";
...
Problem is:
- these roles don't exist,
- they can't be dropped (DROP ROLE "482499"; => FEHLER: Rolle „482499“ existiert
nicht)
- grants can't be revoked (REVOKE ALL ON SCHEMA "user_data" FROM "482499"; => FEHLER:
Rolle„482499“ existiert nicht)
- ROLES can be recreated and dropped afterwards, but the grants persists:
CREATE ROLE "482499";
DROP OWNED BY "482499";
REVOKE CONNECT ON DATABASE "wver_ims" FROM "482499";
REVOKE ALL ON SCHEMA "user_data" FROM "482499";
DROP ROLE "482499";
- new tables can't be created in schemas with these grants
CREATE TABLE user_data.test
(
id serial,
PRIMARY KEY (id)
);
=> FEHLER: Rolle 17708 wurde gleichzeitig gelöscht
The roles are not listed in any catalog
SELECT * FROM information_schema.xxxxxxx WHERE grantee in
('243683','243666','243689','482499','482499','17708');
Only in pg_auth_members there is a set for each of these roles:
SELECT * FROM pg_catalog.pg_auth_members WHERE member in
('243683','243666','243689','482499','482499','17708');
What can I do to get rid of these roles and grants?
Ludwig
