Partially agree. Allow to grant privileges on a database by any selected user!
While creating the snapshot, we created it from a 1-core CPU machine however when we deployed the image, it was a 2-core machine. Before we could realize, we had posted it here!

That is our bad. We'll be more speculative in future to report only after carefully scanning the configs!

This is in fact, on a brighter side, a good sign that despite creating the snapshot on a smaller machine, it works well with other totally different config!
