Re: How to determine offending column for insert exceptions

I'm not sure, but I have a guess, why the column_name is null.
You wrote your queries look like this:

INSERT INTO final_table
SELECT a::int, b::int FROM temp_table

The error comes from the result expression of the select statement where
the source column can't be determined exactly.
