Hi Alex Maiereanu,
Thank you for the update. As you confirmed, the issue was caused by a process that took the PostgreSQL database down. Once that process was addressed, the database recovered and came back online successfully.
The recovery/restore UI in the Azure portal may continue to show an in-progress state for some time, even after the server is already available, which explains the behavior you observed.
Since the database is now online and functioning as expected. Please let us know if you experience any recurrence.
