Well, it doesn't have to match the regression test output exactly --- it
just has to be a valid sample. I never run the regression tests as part
of my testing --- I only load my fixed pg_dump output into the old
database and dump them from the new, and diff.

Well, to do it on the fly, you need to:
use $libdir for regression .so files, not absolute pathschange CREATE OR REPLACE LANGUAGE to simple CREAtE for 8.4run
ittwice to fix inheritance COPY column orderingdeal with extra_float_digits
That sounds tricky.
