I think command status is common and nice feedback for client. I think
it's more simple change something in JDBC than change protocol that is
shared between more tools.

We need some common way how detect on client what's happen on server --
a way that doesn't mean change protocol always when we add some
feature/command to backend. The command status is possible use for this.
