Hi, is it actual for rails 6? [Rails 6 added uuid](https://guides.rubyonrails.org/active_record_postgresql.html#uuid-primary-keys).

I experienced the same problem in the `Arch linux` distribution. Installing `postgresql-libs` helped me. Maybe you need to install a similar package for your system.

Hey @richmolj I could try writing specifications for an ActiveRecord adapter to use this test set afterwards to compare the capabilities of the adapter for Seqeul with the standard adapter...
