No Andreas, no sense parse on client.

After parsing you get a lots of nodes, and it takes longer time to send them
via net. Also on client side you can not do semantic checks of SQL query.
And AST of parsing at last of end should be translated into Execution nodes,
which have sense only on server in context and in RAM of server.
