Upgrade an empty database, then run the regression tests using it.

Test the regression database:

	o  run the regression database against the old cluster
	o  dump the regression database using the old pg_dump
	o  load it into an empty database in the old cluster
	o  dump using new pg_dump
	o  load that into a new database in the old cluster
	o  upgrade the cluster
	o  dump the new database using the new pg_dump
	o  compare against the dump you loaded into the old cluster

It is necessary to dump/load the regression database because
there are slight changes when loading/unloading that need to be removed
before testing for any pg_migrator changes.
