Hi Paul,

Thanks for the review, I've fixed all the issues you commented except

Sorry, it should be in another patch, I added it to wrong place when rebase.

layerquery_all to know all the provided collections in database, so that we
can know whether the dependencies match or not.

Good idea, I will do it later, or you can do it if you have time.
