The question:
I am unable to drop user as I am getting default privileges error.
postgres=# drop user xyz;
ERROR: role "xyz" cannot be dropped because some objects depend on it
DETAIL: owner of default privileges on new functions belonging to role xyz
then I checked default privileges in database,
postgres=# ddp
Default access privileges
Owner | Schema | Type | Access privileges
---- -+------- +----------+-------
xyz | | function |
Could you please let me know how to revoke this default privileges?
The Solutions:
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
Method 1
You have to grant the “default” default privileges:
ALTER DEFAULT PRIVILEGES FOR ROLE xyz GRANT EXECUTE ON FUNCTIONS TO PUBLIC;
ALTER DEFAULT PRIVILEGES FOR ROLE xyz GRANT EXECUTE ON FUNCTIONS TO xyz;
Then you should be able to drop the role.
Method 2
This is the safe sequence of commands to drop a role:
Run in every involved database of the DB cluster.
REASSIGN OWNED BY xyz TO postgres;
DROP OWNED BY xyz;
DROP OWNED
also gets rid of all privileges and default privileges!
Finally:
DROP ROLE xyz;
