Yeah. This will try to create the new latin1test with all the same
properties it had before, including encoding, and 8.3 intentionally
rejects that. Your 8.1 setup is pretty broken too (it will misbehave
in various ways because of the encoding mismatch), but 8.1 fails to
realize that.

Yeah, there's usually little value in -E unless you're planning to
do something else with the dump than just feed it to pg_restore.
(If you wanted to export to some other DBMS, for example, it could
be useful.) In particular -E has entirely zip bearing on what
database encoding will be assigned during restore.
