Not sure if cmdlet review is necessary, but I created an issue regardless. Link: https://github.com/Azure/azure-powershell-cmdlet-review-pr/issues/399

@djnisic a reminder, please update the breaking change suppression file after confirming with us -- we wouldn't want real breaking change to be in the official release.

BTW, I'll look at the PR later. Thanks

Hi @djnisic , sorry for late response.
I was thinking giving an example in readme would be better 🤔
And please see my inline comments. Thanks

Can you expand a bit more on example in readme? I am not sure what exactly do you mean?

What I meant to say was the "Example" section in "Restore-AzSqlInstanceDatabase.md".
