Re: pgAdmin error with new PG15 servers: argument of type 'Response' is not iterable

Hi Steve,

Could you please provide DDL for schema & database?
I could not reproduce the issue. Here is my schema DDL -

CREATE SCHEMA IF NOT EXISTS test123
AUTHORIZATION postgres;

GRANT CREATE ON SCHEMA test123 TO postgres;
GRANT USAGE ON SCHEMA test123 TO postgres WITH GRANT OPTION;

GRANT CREATE ON SCHEMA test123 TO yogesh;

ALTER DEFAULT PRIVILEGES FOR ROLE postgres IN SCHEMA test123
GRANT INSERT, SELECT ON TABLES TO postgres;

ALTER DEFAULT PRIVILEGES FOR ROLE postgres IN SCHEMA test123
GRANT USAGE ON TYPES TO yogesh;

Thanks,
Yogesh Mahajan
