Dear all,

I am currently testing Lakebase for integration in our overall system. In particular I need to enable RLS on a Lakebase table, which is synced from a "Delta Streaming Table" in UC. Setting up the data sync was no trouble, in UC I am the owner of the table. Enabling RLS is somewhat more troublesome. Here is the steps, I have tried (without success):

1. Create a Database role tied to my databricks User, which has all privileges including databricks_superuser (https://docs.databricks.com/aws/en/oltp/pg-roles)
2. Open the SQL-Editor, select the Lakebase instance as compute.
3. Run ALTER TABLE <my-table> ENABLE ROW LEVEL SECURITY; (https://www.postgresql.org/docs/17/ddl-rowsecurity.html)
4. Get an error: "You must be Owner of the table" (Remember, in UC I am the owner).

I assume, that I am missing something here, how the interaction between databricks user and postgres role happens. So what am I missing?

Also: Are there any possibilities or plans to utilize UC Row-Filters with Lakebase (https://docs.databricks.com/aws/en/data-governance/unity-catalog/filters-and-masks/)? Would be nice to have an unified integrated RLS solution for Lakebase tables and Delta tables.

Greetings, Daniel
