v_generate_user_grant_revoke_ddl creates invalid statement.

The output of the v_generate_user_grant_revoke_ddl creates invalid statement because it quotes the object.

ALTER DEFAULT PRIVILEGES for user testuser in schema testschema REVOKE ALL on "tables" FROM testone;
ALTER DEFAULT PRIVILEGES for user testuser in schema testschema1 REVOKE ALL on "procedures" FROM testone;
ALTER DEFAULT PRIVILEGES for user testuser in schema testschema1 REVOKE ALL on "functions" FROM testone;

The expected output should be objects (tables,procedures,functions) without quotes as below.

ALTER DEFAULT PRIVILEGES for user testuser in schema testschema REVOKE ALL on tables FROM testone;
ALTER DEFAULT PRIVILEGES for user testuser in schema testschema1 REVOKE ALL on procedures FROM testone;
ALTER DEFAULT PRIVILEGES for user testuser in schema testschema1 REVOKE ALL on functions FROM testone;

Locate v_generate_user_grant_revoke_ddl and inspect how object names are inserted into generated ALTER DEFAULT PRIVILEGES statements. Reproduce the listed output, then verify generated statements use unquoted tables, procedures, and functions and remain valid.
