Not sure about the else branch here. If there's only one part in a Column instance, isn't that the column name and not a table?

actually yes there's no need for it altogether since if we're here it would have more than one part so table_parts = column.parts[:-1] will be enough

This section seems a little sketchy: part.name gets rid of the quotes, so normalize_model_name will normalize even case-sensitive (quoted) identifiers. Has this been tested / taken into account?

yes the reference_name it compares it too has gone through the same normalisation in get_model_definitions_for_a_path this is why, but I will test further with more edge cases to ensure

revised it to use .sql(0 instead which is used in get_model_definitions_for_a_path as well and added a test for it : test_quoted_uppercase_table_and_column_references

This adds support to detect table references in column expressions for models and ctes (e.g. sushi.orders.customer_id). (needed for: #4718)
