Connected to a RedShift datasource in Toad Data Modeler(TDM) and tried to reverse engineer a model to get multiple errors when extracting information. These can be seen at the bottom of the attached picture. The tables up above are sensibly empty as there’s errors below saying TDM was unable to retrieve column information.
Reference to Toad world :
Ensure it is being using PostgreSQL ODBC Driver and not the Redshift.
