Hi @larry.komenda! The Ad-Hoc feature was deprecated in early 1.10 Airflow versions for security reasons. The deprecation is applicable on both Astronomer + vanilla Airflow images with RBAC enabled (which is true on Astronomer).
We have a ticket internally for our team to build out a new way to test connections, as it’s a feature a lot of our customers used to take advantage of. With that said, it’s not actively in the works and I can’t give a concrete update for when a feature like that would be available.
If you happen to want to query your own Metadata Database (a common use case for the Ad Hoc Query tab), we have instructions on the best way to set up that connection and test it here: astronomer.io/docs/query-airflow-database.
Hope that answers your question, @larry.komenda!
