```pgsql
-- testing script
LOAD 'age';
SET search_path = ag_catalog, "$user", public;
SELECT create_graph('g');
SELECT create_distributed_table( 'g.ag_label_vertex', 'id' );
-- throw: data type ag_catalog.graphid has no default operator class for
specified partition method
```
I tested follow script with below dockerfile script.
and, it need to support from citus, because of `currently only support using
the default operator class`
