-d option in pg_dump

Hi -

In previous versions of postgres (8.1, 8.0), we had problems loading
some data from dumps that were used the copy command rather than the
insert command. If I remember correctly, these problems were caused by
weird characters in some of the data values. As a result, we tend to use
the -d option with pg_dump. At this point our databases are taking too
long to reload using inserts. I did some testing and haven't run into
the problems with the copy commands but don't want to find out that I
was wrong when I'm trying to restore from a failure.

Were there changes made some time before 8.2.4 that made loading pg_dump
with copy as safe as with insert commands? Have other people had
problems restoring databases from pg_dump without the -d option?
