It says right here. You forgot to move your old data directory out of
the way. As it's from a Postgres 8.3 installation, Postgres 8.1 has
no way of knowing how to handle what's in there.

Because initialisation of the database (initdb) failed for the
aforementioned reason. There are probably some messages in your logs
about postgres failing to start or to operate on its data directory.
You can't just run a different major version of postgres on an
existing data directory.
You didn't tell what your goal is. Are you trying to downgrade an
existing database? If so, why would you want to do that?
