-----------------------------------------------

Hi Vladimir

I suppose the open issue is related to aggregation over cluster. My naive implementation does
not take into account aggregation over cluster. But anyway I have no comments or suggestion
on my pull request. Currently I have no interest in this pull request. Feel free reassign
it.

> It is possible to add user defined function (@QuerySqlFunction annotation) for H2 SQL,
but it is not possible to add user defined aggregate. For consistency I suggest create new
annotation @QuerySqlAggregateClass
