"PG" Branch

[schwarzh]

I was excited to see a new branch in this repo, created by @ljachymczyk . I tried this new branch in my Rails 6.0 app (which we recently updated from Rails 5.0), and have been unsuccessful in getting it working so far. I'm wondering what the status is of this branch. If the branch is in working order, are there setup instructions you could offer that are different from the current readme? It appears that the syntax for this new branch may be fairly different from the master branch.

Thank you so much for your hard work on this repo!
