Wouldn't it be easier just setup unique roles for each database? It's much
better solution than deploying 10 separate clusters (which you'll learn
soon, if you go in this direction).

And what are those "some problems" that you mentioned? Seems to me this
thread started from the wrong end - setting up multiple clusters instead
of tackling the actual problem first.
