REE type coercion not working correctly #18516
Description
Describe the bug
I am working with data that is REE encoded, and ran a SQL statement like:
SELECT * WHERE ree_encoded_column_name = 'test'
Which resulted in the following error:
Something went wrong: rpc error: code = Internal desc = Failed to execute stream: type_coercion%0Acaused by%0AError during planning: Cannot infer common argument type for comparison operation RunEndEncoded(Field { name: "run_ends", data_type: Int32, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }, Field { name: "values", data_type: Dictionary(UInt32, Utf8), nullable: true, dict_id: 1, dict_is_ordered: false, metadata: {} }) = Utf8
The column is an REE encoded dictionary of strings.
I'm not 100% sure this issue belongs in datafusion or arrow, feel free to let me know if arrow is more appropriate and I can move it.
To Reproduce
Create a table provider that emits records with REE arrays and run a filter on it.
Expected behavior
It filters/coerces as expected.
