OK, the attached patch installs plpgsql by default from initdb, and
supresses the dumping of CREATE LANGUAGE in 8.5 and in 8.3/8.4 if binary
upgrade is used (because you know you are upgrading to a release that
has plpgsql installed by default). The 8.3/8.4 is necessary so the
schema load doesn't generate any errors and cause pg_migrator to exit.
