Function object_name_to_table_reference

datafusion/sql/src/planner.rs:919–937

Create a [`TableReference`] after normalizing the specified ObjectName Examples ```text ['foo'] -> Bare { table: "foo" } ['"foo.bar"]] -> Bare { table: "foo.bar" } ['foo', 'Bar'] -> Partial { schema: "foo", table: "bar" } <-- note lower case "bar" ['foo', 'bar'] -> Partial { schema: "foo", table: "bar" } ['foo', '"Bar"'] -> Partial { schema: "foo", table: "Bar" } ```
