Hi hackers,

While playing with pg_regress and pg_isolation_regress, I noticed that
there's a potential nullptr deference in both of them.

How to reproduce:

Specify the `--dbname=` option without providing any database name.

<path>/<to>/pg_regress --dbname=   foo
<path>/<to>/pg_isolation_regress --dbname=   foo

Patch is attached.

Best Regards,
Xing
