   Thanks for your PR. This is indeed a problem.
   But I think it could be better to handle this situation in `StmtExecutor.handleQueryStmt()`.
   Because here we have analyzed the statement, and all constant exprs has been calculated, so that we can simple check
   if there is no table ref in statement and all select items are constant literal, and there is no alive backend, then return the result by FE.
   This can cover more situation than only handle `select version()` and `select @@variables`;
