I don't know offhand since I didn't write that code. However if you google for "pg_get_expr 128", there's a ton of other hits illustrating this same expression being used elsewhere. I believe the statement itself comes from Postgresql itself ultimately, if you look at this answer: http://stackoverflow.com/a/5371745/34549
Can you try removing the substring() and seeing if this function in fact returns the whole default as you're looking for?
