I realized that PostgreSQL can listen to both the Unix domain socket and a TCP address so I've been able to run the tests. I'm stuck now with the integration tests failing because they can't run the Selenium Chrome webdriver. I opened an issue. I also have some failed tests on a model, still didn't looked at them.

I won't convert this app to Sequel only to check that it works with JRuby. Neither I'll write the next one with Sequel. If JRuby doesn't handle AR it's over for me. It's JRuby that must be compatible with MRI (the reference implementation of the language), not the other way around. That until the majority of rubyists use JRuby as default. It's too risky.
