Hi,
I found an issue in *connnection* function in
utils/drivers/psycopg2/__init__.py file related to 'datlastsysoid'.
It was not getting retrieved and put inside db_info dict.
Due to this error occurred while expanding cast collection node.
I have resolved the issue and attached a patch with this mail.
Please do review it.
Regards,
