PostgreSQL restricts acces to the salt and shift via the SHOW command for users not member of pg_read_all_settings. But they are visible in pg_db_role_setting or pg_roles if they were set on the database, user or both. PostgreSQL Anonymizer's documentation recommends to use ALTER DATABASE / ALTER ROLE for the salt. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
