support for UUIDs

[adriand]

Rails supports UUID primary keys in Postgres (https://guides.rubyonrails.org/active_record_postgresql.html#uuid-primary-keys), but UUID id fields are not properly serialized. The show up in types as 'unknown'. They should, I believe, be serialized as strings.

I'm working around that with code like:

  attributes :kind, :service, :name,
             id: { type: :string }, flow_id: { type: :string },
             connection_id: { type: :string }, webhook_id: { type: :string },
             mapping_id: { type: :string }, transaction_set_id: { type: :string }

But it would be nice if this feature was natively supported.

Hi Adrian!

Happy to accept a PR mapping uuid to the string type in the default mappings.

See this example PR, which added types for citext.

Done!
