If we're going to test in a non-Perl language, I'd pick C over Python. There
would be several other unlikely-community-choice languages I'd pick over
Python (C#, Java, C++). We'd need a library like today's Perl
PostgreSQL::Test to make C-language tests nice, but the same would apply to
any new language.

I also want the initial scope to be the new language coexisting with the
existing Perl tests. If a bulk translation ever happens, it should happen
long after the debut of the new framework. That said, I don't much trust a
human-written bulk language translation to go through without some tests
accidentally ceasing to test what they test in Perl today.
