Hello Shailendra Singh
When a server is deleted, database server backups may be retained within the service for up to 5 days.
We ask that you follow the following documents to restore your server, https://learn.microsoft.com/en-us/azure/postgresql/flexible-server/how-to-restore-dropped-server
pgaudit extension provides detailed audit logging which is not enabled by default.
- Server logs capture (PostgreSQL standard logs) must be enabled explicitly to access logs for troubleshooting, monitoring, and audit-level details.
- Azure monitoring and PostgreSQL logging features are available independently of pgaudit but require server logs capture and diagnostic settings to be enabled.
- Thus, without enabling pgaudit and server logs capture, you cannot find the logs to check the server deletion details.
