Hi @Sławomir Nowak Thank you for posting your question on Microsoft Q&A and for using Azure services.
As per my understanding you are facing some issue creating a PostgreSQL flexible server using terraform or manually.
There is an outage going one for customers creating Azure PostgreSQL flexible server. Our product Group are actively working on it.
Existing servers are not impacted. Only PITR and new server creations are impacted.
