What versions of Erlang/Elixir and PostgreSQL were used for the book’s code examples? Naturally, lots of changes have happened in the couple of years since it was published and working with the versions in use at the time will make the examples work without too much heartburn.

Erlang/OTP 22, Ecto 3.0. I’ll ask the authors about the possibility of a new edition. Postgres, it looks like the book was published just before v12, so probably 12, but possibly 11.
