Both instances are valid here, and there is no mechanism to choose one of them.

There is: OverlappingInstances[1] chooses the most specific instance. So in case someVector :: Vector Word8 the instance Show (Vector Word8) is chosen because it's the most specific.

Although I don't have a problem with using language extensions the vector package, as it is a commonly used tool, shouldn't require me to use an extension just to be able to debug my code. This would be particularly annoying when using GHCi, because you would always have to start it with an extension option.
