Hehe, funny thing is I realized that after I went home last night... For
some reason I took out my calls to PG_DETOAST_DATUM at some point... I
havn't a clue as to why, but oh well.
I need to go test this to verify, but I am 90% sure that is the problem.
Can someone explain to me why one works and not the other without
PG_DETOAST_DATUM?
Also can someone tell me how to easily tell how much data for a
particular table is being toasted?
Thanks guys!
Morgan

In tests I see different behavior between SELECT and COPY if the
type's output function doesn't call PG_DETOAST_DATUM on its argument:
SELECT returns the correct data but COPY doesn't. Have you neglected
to call PG_DETOAST_DATUM?
