I'm not parsing that. Why do you need an explicit cast?

If I want to handle csv data in an array, I usually do it like this:
*) create a one column table for staging the load
*) COPY the data to that table, intentionally faking the delimiter
*) process via conversion to array with 'string_to_array'.
the above only works if there's no commas inside your strings, so a
little extra massaging might be required in that case.
