I meant to mention this during previous discussion.
Currently the pg_regress script does "dbname=regression" and then does
everything in terms of $dbname. Would there be any value in providing a
--dbname=foo parameter so that different regression sets could use their
own db? One virtue at least might be that we would not drop the core
regression db all the time - having it around can be useful, I think.
