Thanks for the question and using MS Q&A platform.
I'm sorry to hear that you're encountering issues with your serverless databases in Azure Synapse Analytics. The "Recovery Pending" state indicates that the database is in the process of recovering from a failure or restore operation. This process can take some time, depending on the size of the database and the amount of data that needs to be recovered.
To gain insights into the cause of the recovery delay, you can check the Azure portal's Activity Log for any relevant error messages or notifications. You can also try to recreate the databases by exporting the data and importing it into a new database.
Additionally, you can check this thread which addressing similar issue: How to fix Recovery Pending databases in Synapse SQL Serverless pool.
