pg_dump versions more recent than 8.4 use "CREATE OR REPLACE PROCEDURAL
LANGUAGE" to work around the possibility that plpgsql is preinstalled.
If you don't want to use a modern pg_dump, you'll need to not use
--exit-on-error.
In general, it's recommended to use the newer pg_dump when trying to
transfer data from an older installation to a newer one. You can
generally make it work without that, but it's not necessarily going
to be seamless, and one of the ways it tends to not be seamless is
that you have to be willing to ignore harmless errors.
