Backup Restore fails if we use same name as source db pod

@dosu
I am using CNPG 1.26 with Barman Plugin 0.11.0 on ak8s.

I taken the backup of one of DB cluster on azure blob stoarage.

I restore db with different name from that backup and it worked.

Now i deleted that original db . tried to restore db from backup with same db cluster name and it is failing. why we cannot use same db name.

Start by reproducing the restore with CNPG 1.26 and Barman Plugin 0.11.0 on Azure Blob Storage, using the same cluster name after deleting the original. Collect the restore failure output and compare it with the successful restore under a different name; done means identifying the cause and confirming whether same-name restoration works or documenting the limitation.
