As far as I can find from a quick look through the CVS logs, no
data-mangling bug in COPY has been reported or fixed since before 7.4
(at least in the mainline code --- CSV mode has had some teething pains,
but pg_dump has never used CSV mode). The last patch I can find that
addressed any such problem was here:
http://archives.postgresql.org/pgsql-committers/2003-10/msg00050.php

If you've had issues since then, you really should have filed bug
reports.
