What Permission Set Is Required For This Scenario?

Question

Hello,
I currently have an environment where I have limited users to being able to create/delete databases that only they have created.  I did this by creating a Login with Public access and granting them the  CREATE ANY DATABASE permissions to their
login. This works great as the users can create a database and delete their database but not anyone else's. The issue I have is the following scenario:
Database A is backed up from Server 1 (a different server than the restore server) and the DB was created by User 1
Database A is restored to Server 2 by User 2 who has CREATE ANY DATABASE permission (successfully).
User 2 can see the restored database, but cannot access it: The database is not accessible error.
When I view the database I see that the DB Owner is listed as User 1.
I've been trying to figure out how to be able to allow the user to become the new owner so they can edit/delete the database, but still not affect other databases that they do not own.
I've played with various permission sets but they end up being able to delete other user databases which I'm trying to avoid.  I also don't want to have to change the owner myself. 
Is there a permission set that I can grant that will allow this scenario?

Answer 1

That's a valid statement, let me explain my scenario and perhaps there is a better way to construct what I'm after.
I have a QA server where different developers create databases.  All the databases backed up on the QA server are stored in a shared folder.  This shared folder is accessible on our DEV server.  We have a different set of developers
who at times need to restore one of the QA backups on the DEV server for different testing reasons.  The permission set applied was simply to prevent someone from accidently deleting someone else's database.  Restoring someone else's database in
our environment is not a concern.
With this in mind, I was hoping there was an additional permission I could grant that would allow the user restoring the database to become the new owner. I don't want the burden of approving it as it will always be approved.
I clicked on the connect link, but it returns as invalid -
