### What feature or improvement would you like to see? SchemaTableColumn.ProviderType specifies the **provider-specific data type** of the column, so the following code: arrow-adbc\csharp\src\Client\SchemaConverter.cs line 64: `row[SchemaTableColumn.ProviderType] = SchemaConverter.GetArrowTypeBasedOnRequestedBehavior(f.DataType, structBehavior);` should be changed to: `row[SchemaTableColumn.ProviderType] = f.DataType;`. Otherwise, the original service data type information (whether it is struct) of connectors such as GBQ will be lost. I noticed that you wrote SchemaConverter.GetArrowTypeBasedOnRequestedBehavior() to handle the conversion from struct to string. I understand that data type conversion is a normal behavior, but it should only modify SchemaTableColumn.DataType, not SchemaTableColumn.ProviderType. I don't know if my understanding is more reasonable, so I raised this issue to discuss with you. -- This is an automated message from the Apache Git Service.
