Hi, I can do it. @universalmind303 can we create unary union after parsing sql query? I think that `SELECT * FROM FOO UNION` is not a valid query. @alamb this logical optimization already exists in `LogicalPlanBuilder::union` method, should it be rewriten as logical optimizer step and removed from `LogicalPlanBuilder::union`? -- This is an automated message from the Apache Git Service.
