### Is your feature request related to a problem or challenge? In `datafusion-sqlparser-rs`, we define many SQL types but they aren't all required by the DataFusion core. https://github.com/apache/datafusion/blob/b0b6e4427fd6bd64fc29e521c43d86206d2e4ea7/datafusion/sql/src/planner.rs#L524-L529 I think it's good to provide a way to extend or customize the behavior for SQL type to DataFusion type (maybe changed to `NativeType` in the future) for the downstream project that may want to use those unsupported SQL types. ### Describe the solution you'd like Introduce a new API for `ExprPlanner`, ``` /// Plan SQL type to DataFusion data type /// /// Returns None if not possible fn plan_data_type(&self, _sql_type: &ast::DataType) -> Option<DataType> { None } ``` Try planning the SQL type using `ExprPlanner` first. If not present, revert to the default behavior. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
