Thanks for your feedback. I’ve tried connecting to PostgreSQL using the ADBC method, but unfortunately the SAP Kernel doesn’t have the corresponding .os (DBMS) file, so the connection could not be established. May I ask if connecting via ADBC is actually feasible in this case?
That's a little too vague of a question, but yes, Postgres should be able to handle things just fine. The amount of SAP tools and SAP-supporting ETL tools that also support Postgres should be a strong encouragement. I'd recommend looking at the specific tools you would use and confirming they have Postgres support built in. Then try and find use cases / complaints for those specific items.
