hi Sebastian Loef & thx for sharing urs issue here at Q&A portal,
This is platform-side now.
A PostgreSQL Flexible Server stuck in Starting for 24+ hours after a compute resize is not normal, and there usually isn’t a safe customer-side fix for that state. Don’t keep retrying random changes in the portal. Open an Azure support ticket and include server name + region+subscription ID+timestamp of the resize+old/new compute SKU+current provisioning/state & any operation/correlation ID from Activity Log.
If u have backups or a replica and the RTO is urgent, ask support whether restore-to-new-server is the fastest recovery path. But the stuck server itself needs Microsoft backend intervention.
rgds,
Alex
