Because it's a lot easier for `pg_regress --load-language=plpgsql` to mean "ensure the language is installed" than it
isfor 3rd-party test suites to detect what version they're being installed against.
Really, all that has to happen is pg_regress in 8.5a4+ needs to just ignore `--load-language=plpgsql`. That's it.
