Are you sure?  I know people asked up-thread for the output of \l, but
I haven't seen it.  If your encoding is UTF-8, then I don't understand
how you got non-UTF-8 characters in there, unless there's some bug in
the 8.2 series of which I'm unaware.

You shouldn't have to.  That's a constraint on sorting and such like.
It doesn't control what can get into the database.

Hmm.  I wonder if the problem is the locale you're using for pg_dump
vs. what you're using when handing the data back in.  If the locale
were different, it might be possible that your client_encoding was
different.  I have no idea if this is the case, but you might want to
try it.  Check your locale at the command line on each system.

As I said before, if the database encoding is UTF-8, then it's
supposed to be _impossible_ that you get non-UTF-8 data in there.
That's the whole point of having the database encoding.
