Basically there isn't much extra work to go from 8.3 to 8.4 compared to
8.3 to 8.5.  Now, if could support only 8.4 to 8.5 I could remove some
code, but that seems counterproductive.

The other problem with moving to /contrib is that I can't put out
pg_migrator updates independently of the main community release, which
could be bad.

I am glad some people think pg_migrator is ready for /contrib.
