I'm using the Unparser.expr_to_sql function to translate a DataFusion Expr into an expression for Spark Connect. Unlike most SQL engines, Spark doesn't like quoting the column identifiers. I want to be able to generate an expression like a > 4 but currently I can only get "a" > 4
I believe this might be useful beyond Spark for other database systems that can handle unquoted column identifiers.
