Maybe this could be done by creating a pg_dump ?

The dump could be grepped (like pg_restore -l |perl -pe '/ROLE|.../')
for offending objects.

And the dump could be re-used for other things, like not re-running
regression tests in pg_upgrade and 027_stream_regress.

I don't know whether the pg_dump would be run directly by pg_regress or
something else.
