Boolean parsing is broken with Postgres

[backspace]

I’m not opening this to actually be merged, just to highlight the problem. I found that I couldn’t get a true value from a boolean field and it seems like a difference between what’s returned from the in-memory SQLite database in tests vs Postgres.

It’s possible the Boolean(value) change is sufficient but there’s a lot of ceremony here just to get tests running on CI with Postgres, I don’t know that it’s worth having it all, or if it is, it would need to be completed.

• it was using UUIDs and failing because the hard-coded IDs were invalid
• my attempt at overriding generateId failed
• so I limited it to run one test and changed the setup data to use UUIDs

I showed it failing when I added a boolean to the schema and made its value true in the example author. Then it passed with the change to boolean handling.
