I don't think we need testing, per se.  The first step should be to
diff
the 8.3 and 8.4 versions of the various contrib .sql.in files and
determine what changed. Any module whose .sql.in file hasn't changed
is definitely safe.

I can tell you already that dblink has changed, and I had to drop it
before migration, otherwise everything went fine. Migration of 57GB
data in place took about 1 minute.

The good news is that the INSTALL instructions where clear enough for
the tester to understand that uninstalling dblink from the old cluster
and reinstalling it in the new cluster would work.
Yes, but I forgot about one database, and had to do it all over again, luckily I first tested it without --link...
