> Currently we do not support {{CHECK}} constraint, which is very important in 
> SQL world. Need to investigate how we can add it. Essentially, we have two 
> ways:
> 1) Either delegate constraint validation to H2 somehow. But remember that we 
> should do that early during update, and we should do that efficiently. Need 
> to investigate H2 API to find out how to achieve that.
> 2) Or we should wait for development of our own execution engine, which is a 
> huge thing and would not appear fast. In this case we would be able to 
> pre-compile expression somehow and execute it whenever we want.
