Hi @pesky_chris!

Are you otherwise able to access your federated Postgresql data via the Serverless SQL Warehouse (e.g. using a SELECT statement)?

If not, your issue may be due to networking/firewall between the Serverless SQL Warehouse and your Postgresql server.

Here is some info on configuring private connectivity for serverless: https://learn.microsoft.com/en-us/azure/databricks/security/network/serverless-network-security/serv...
